%%* ''Manga/CaseClosed'' uses this method to gather clues occasionally.

* A circa '70s ''Archie'' story had Big Moose going missing just before a big baseball game with Central High. Archie and Jughead trace Moose's recent whereabouts to a telegram office where Moose received a handwritten note. Archie used the indentation clue method to find out Moose was at the bus station waiting to go to the city where a family matter called him. It turns out that it was a Central High trick to get Moose out of the game. Archie and Jughead transport an incensed Moose back to Riverdale where he cleans up Central High virtually single-handed.

* In ''Film/NorthByNorthwest'', Thornhill is able to figure out where Eve is going by finding the impression of an address she wrote.

* Used in ''Film/CloudAtlas'' to figure out the address of a murdered scientist's daughter.

* ''Film/TheFourthProtocol'' is about a Soviet plot to detonate a nuclear device on British soil and MakeItLookLikeAnAccident. As such an act violates a secret protocol between the nuclear powers, various people get bumped off because [[YouKnowTooMuch They Know Too Much]]. A female military scientist is sent to assemble the bomb that the KGB agent played by Pierce Brosnan will detonate. She delivers a message which Brosnan decodes using a one-time pad, then he burns the message claiming that it just confirms her instructions (re: setting off the bomb). She ends up sleeping with him, and the morning after rolls over in bed and sees the imprint on the notepad: KILL HER. Brosnan immediately shoves a pillow against her chest and fires his gun through it.

* In the Mexican film ''Film/LaHabitacionAzul'', this is how the cop of the movie discovers a message Andrea sent to her lover after her husband died, saying "Now it's your turn"; he uses it to accuse Andrea of murdering her husband and egging her lover on doing the same with his wife.
* In ''Film/{{Tusk}}'', detective Guy Lapointe uses this method to reveal an address Wallace had written down on a note pad before his subsequent disappearance. Teddy notes that he recognizes the trick from ''Film/TheBigLebowski'', and Lapointe admits that's where he learned it.
* In ''Film/{{Paddington 2}}'', Mary sneaks into [[BigBad Phoenix]]'s apartment and uses this trick to obtain the location of the MacGuffin which he wrote down on a notepad earlier.
* ''Film/AnimalHouse'' has the Deltas trying to steal the mimeograph stencil ([[Main/TechnologyMarchesOn look it up, youngsters!]]) of a mid-term exam, so they can do well in the class without having to actually study the material. Unfortunately, the Omegas had already stolen the actual stencil and substituted a fake stencil with all of the answers being wrong.

* Mentioned by Franchise/SherlockHolmes when telling Watson how he got his information as "[[LoveLetterLunacy a fact that has dissolved many a happy marriage]]". However, in this case, he uses the blotting paper to obtain the reverse message, as the writer had used a pen.

* The psychokinetic children in ''Literature/FromTheNewWorld'' are given their own mantra and told to keep it a secret, but the heroine was curious enough to persuade her classmate into writing down his mantra and giving her a glimpse of it. She couldn't see it clearly, of course, but she read it by shading the sheet underneath with a pencil after he left.
* In ''Literature/BulldogDrummond'', a mook assigned to trail Drummond uses this to find out what Drummond wrote in a telegram--but reveals a rude message from Drummond, who'd realised he was being followed.
* Mentioned briefly in the book version of ''Literature/TheTimeTravelersWife''; this is how Clare discovers Henry's intention to get a vasectomy.
* Played with in ''Literature/{{Jingo}}'', part of the City Watch subseries of the ''Literature/{{Discworld}}'' books. Someone had written a note on a pad of paper, but someone else came along and took the next few pages to prevent anyone else using this technique. Vimes addresses the resultant FridgeLogic: Why didn't he just take the whole pad? Because he also wanted Vimes to be curious about the contents of the note.
* ''Literature/TheDresdenFiles'': In ''Literature/DeathMasks'', Harry Dresden recovers a thief's notepad after seeing her tear off the top page. He shades the page underneath it with charcoal to find out what she'd written.
* In ''Literature/TheDeathOfAchilles'', Fandorin figures out the bad guy's address by tracing the indentation in a notepad he found on the scene.
* A variant is used in ''Literature/HalfMoonInvestigations'': when his sister Hazel brings him a note from her boyfriend that doesn't sound right, Fletcher notices several pieces of evidence that point to the note being erased and rewritten several times on the same sheet of paper. He takes a pile of graphite shavings, spreads them across the paper, and slowly shakes them off. Some of the shavings get caught in the dents from the erased notes, allowing them to be read. Hazel's boyfriend is in an affair and started writing a break-up note before erasing it and trying something gentler.

* This is the key to Steve Berry's ''The Third Secret'', based on the visions of [[https://en.wikipedia.org/wiki/Our_Lady_of_Fatima Our Lady of Fatima]]. In reality, three children saw the Virgin Mary and heard her confide [[https://en.wikipedia.org/wiki/Three_Secrets_of_F%C3%A1tima three secrets]]. Two were revealed later, with the [[https://en.wikipedia.org/wiki/Our_Lady_of_Fatima#Third_Secret third secret]] not to be opened until after 1960. It was read by [[UsefulNotes/ThePope Pope John XXIII]] and by subsequent popes, but wasn't made public until 2000. In the novel, John can't read Lucia's old-fashioned Portuguese, so he gets a translator to write it in modern Portuguese and in Italian. The translator has a very heavy hand and his writing is impressed on the page below; moved by an interior impulse, he later shades out the impressions and keeps them. This is the "facsimile" that he later sends to Pope Clement VIII, and this is where the story really starts.

* ''Literature/TheBerenstainBears'': Used in the Big Chapter Book ''The Berenstain Bears and the Bermuda Triangle'', revealing that Bermuda had copied down what appears to be a phone number. It's actually the number to the in-school modem, letting someone log into the school's private network and steal information from his teacher's files.
* ''Literature/SherlockHolmesAndDoctorWasNot'': In "The Sign of Two", Holmes rubs a pencil over the top sheet of Dr. Jekyll's notebook and is able to bring up some of his notes: enough to give him an indication of what he is working on.

* In an episode of ''Series/LoisAndClark'', Clark uses his powers to read several messages indented on a wooden desk.
* In the ''Series/{{Eureka}}'' episode "Before I Forget", Carter starts to write a ticket for the villain of the week, only to be given LaserGuidedAmnesia and have the ticket stolen. Later he works out this happened and uses this technique to recover a partial license plate. Amusingly, Henry starts to talk about a high-tech method he can use to recover it, only to trail off as Carter does it.
* Found in an episode of ''Series/{{Shark}}'' with two variations: the first being that it's not a text, but a drawing, the second that the detectives don't use a pencil to bring it out, but [[EnhanceButton a computer]].

* In an episode of ''Series/{{Monk}}'', "Mr. Monk Takes His Medicine," Monk suspects that something is wrong with suicide victim Marlene Highsmith's suicide note. At first, he doesn't seem to know or care what is wrong because he is on Dioxynl, but when Monk goes off the drug, he realizes that the note was not Marlene's because it was written with a red pen, and there is no red pen in the kitchenette the note was written in. Monk takes the writing tablet the note was written on and uses chalk rubbing to reveal Marlene's actual suicide note - a confession that her ex-husband Lester Highsmith is staging an armored car robbery, that happens to be going down right at the moment Monk and Sharona discover the note. Lester had written the suicide note the police found and staged a drive-by shooting a few blocks away to keep the cops away while he switched out notes.

* ''Series/{{Columbo}}'':
** In the episode "Now You See Him", the Great Santini shoots Jesse Jerome immediately after Jerome types a letter exposing Santini as a wanted war criminal named Sgt. Stefan Mueller. Columbo catches Santini by examining the typewriter ribbon, which contained an impression of all the keys the victim had pressed.
** In "Columbo Likes the Nightlife" Justin Prince removes a page from Linwood Cobin's calendar to remove evidence of Cobin's extortion scheme, but this just raises Columbo's suspicions since it's strange someone would remove a calendar page before a "suicide". As it turns out, the indentation is still there.
* In ''Series/{{Angel}}'', when Cordelia's missing, Angel suggests trying this with her memo pad to see what the last message she wrote down was. [[SubvertedTrope Gunn counter-suggests checking the carbon copy.]]
* ''Series/{{NCIS}}'': [=McGee=] is a writer who still uses an old-fashioned typewriter. [[spoiler: A LoonyFan steals his used typewriter ribbons and commits murders inspired by the plot.]]

* ''Series/MurdochMysteries'':
** In the episode "Buffalo Shuffle", Murdoch uses graphite shavings from a pencil sharpener to raise some letters from a sheet in a notebook. He only finds some characters, so the meaning of the clue isn't readily apparent.
** In the episode "High Voltage", Murdoch asks a hotel desk clerk about the occupant of a hotel room, and the clerk finds the relevant page from the hotel register is missing. Murdoch uses this method and a camera to recover a signature from the register's next page.
** [[TyrantTakesTheHelm Chief Constable Davis]] uses this in "Bloody Hell", not realizing [[spoiler:Murdoch was setting him up]].

* ''Series/BlakesSeven''. In "Killer", Avon and Vila blackmail a technician into helping them commit sabotage; however, he writes out a message (because Avon and Vila are listening in the next room) and hands it to an underling to be transmitted to Star Command, warning them of the rebels' presence. Later the technician crushes up the remains of a thermal bomb to avoid leaving evidence behind. As Vila is sweeping up the soot, he notices the pad used earlier and covers it with the soot to read the message.
* ''Series/TheDoctorBlakeMysteries'': In "First Dance", Lucien finds the last page of the VictimOfTheWeek's algebra exercise book has been pulled out. Lucien rubs a pencil over the sheet underneath to find the impression of a blackmail note she had been composing.

* An episode of ''Series/{{Bones}}'' has them use a high tech version of this to recover the writing from a blood-soaked notebook.
* In the Discovery Channel's miniseries ''Series/ManhuntUnabomber'' (about the search for the Unabomber) has a RedHerring with this. One of the early leads is that the words "Call Nathan R." were indented on a document sent from the Unabomber. It turns out that one of the first people handling evidence wrote a Post-It note on top of the letter, so the indentation was not from the bomber.
* ''Series/MidsomerMurders'': In "Death in a Chocolate Box", Barnaby rubs a pencil over the notebook in the VictimOfTheWeek's office to discover the last thing he wrote was a letter. Although Barnaby only gets the last part of the note, it is enough to tell him the letter exists and may have been the reason why he was murdered.
* ''Series/FatherBrown'': In "The Devil You Know", Father Brown rubs a pencil over the notebook of the VictimOfTheWeek to bring up most of a note he had written and then torn out and sent to the War Office.
* A variation in ''Series/Batwoman2019''. The title character is knocked down by a truck driven by the VillainOfTheWeek. Fortunately the Batsuit records deformation impact data--as from bullets or blunt force trauma--which software can then analyze to reveal patterns, so part of the license number is recorded this way.
* Anytime ''Series/DrQuinnMedicineWoman'' has needed to invoke LoopholeAbuse to get the local telegraph operator to tell her about a message that he sent (he's taken an oath to keep such communications private), she'll usually take the notepad that he wrote the message on and shade it to find out what was transmitted.

* Used by Lee in one episode of ''VideoGame/TheWalkingDead'' to get instructions for how to drive a train from a ripped notepad.
* Cole uses this trick to gather evidence for a few cases in ''VideoGame/LANoire''.

* In ''VisualNovel/DanganronpaTriggerHappyHavoc'', this is used in solving the first case, as there was a note passed between the culprit and victim that reveals that [[spoiler:the victim called the culprit to "her" room (actually the main character's, because they'd swapped rooms) intending to kill him, only to wind up being the one killed when her would-be victim defended himself]]. One of the students even recognizes this trick from TV.
* In ''[[VideoGame/SeasonOfMysteryTheCherryBlossomMurders Season of Mystery: The Cherry Blossom Murders]]'', this provides evidence of what (and who) the protagonist's husband had been looking into before his alleged suicide.
* Used in ''VideoGame/{{Scratches}}'', when Michael reveals a letter from the former maid of the mansion to her family, in which she details her account on the events that happened in the mansion and revealing the location of a secret compartment.

* It took nine games including all spin-off games, but this trope finally appears in the ''Franchise/AceAttorney'' series, in ''[[VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice Spirit of Justice]]''[='s=] DLC case.
* Used by Karl Fairburne in ''VideoGame/SniperEliteV2''. Karl's investigating locations of V2 rocket launch sites in Berlin.

* This is the key to Steve Berry's ''The Third Secret'', based on the visions of [[https://en.wikipedia.org/wiki/Our_Lady_of_Fatima Our Lady of Fatima]]. Two of three secrets she entrusted to the children were revealed at the proper time, but the [[https://en.wikipedia.org/wiki/Our_Lady_of_Fatima#Third_Secret third secret]], while opened by [[UsefulNotes/ThePope Pope John XXIII]] and by subsequent popes, wasn't made public until 2000. In the novel, John can't read Lucia's old-fashioned Portuguese, so he gets a translator to write it in modern Portuguese and in Italian. The translator has a very heavy hand and his writing is impressed on the page below; moved by an interior impulse, he later shades out the impressions and keeps them. This is the "facsimile" that he later sends to Pope Clement VIII, and this is where the story really starts.

* ''Manga/DetectiveConan'' uses this method to gather clues occasionally.

->''It is a pity he did not write it in pencil: as you have no doubt frequently observed, Watson, the impression usually goes through- a fact which has dissolved many a happy marriage.''

''Film/AnimalHouse'' has the Deltas trying to steal the mimeograph stencil ([[Main/TechnologyMarchesOn look it up, youngsters!]]) of a mid-term exam, so they can do well in the class without having to actually study the material. Unfortunately, the Omegas had already stolen the actual stencil and substituted a fake stencil with all of the answers being wrong.

Two of three secrets she entrusted to the children were revealed at the proper time, but the [[https://en.wikipedia.org/wiki/Our_Lady_of_F%C3%A1tima#Third_Secret third secret]], while opened by [[UsefulNotes/ThePope Pope John XXIII]] and by subsequent popes, wasn't made public until 2000.

This is the "facsimile" that he later sends to Pope Clement VIII, and this is where the story really starts.

In certain genres and at certain times, this trope has been common enough that a savvy villain might take steps to avoid it, such as by taking several sheets from a notepad, or slipping a piece of cardboard between the top two sheets, to prevent the pesky detective from doing this.

A number of variations on this exist--for example, it isn't always paper that the indentation gets made on. A similar concept from the time when writing involved a lot of wet ink was to look at the [[http://en.wikipedia.org/wiki/Blotting_paper blotting paper]] (used to absorb excess ink). Carbon-copy and triplicate-copy paper are designed to take advantage of this, allowing the impression to release ink so that multiple copies are written or typed at once.

* In ''Manga/DeathNote'' it becomes vitally important in the final storyarc. Light has had the Death Note for so long, using it to become the mass-murderer (and in his mind, Living God) "Kira" (Killer), and been able to successfully dupe for so long the police team that he's a member of which is meant to hunt Kira, that he gets, well...overconfident and sloppy. He has meetings with one of his new catspaws, which he realizes are being recorded by hidden microphones, so he has seemingly normal conversations with her in their hotel room, while passing her hand-written notes giving his real Kira-directed instructions. Unfortunately for him, his police colleagues ''finally'' grow suspicious of him - well, he was always one of the top suspects to be Kira, but he managed to trick them with so many fake alibis that they had long since written him off as a red herring. At any rate, one of them later goes into the hotel room he was in, and uses the writing indentation clue on the notepad he was writing instructions to his agent on -- Light grew so overconfident that he stupidly forgot about this little trick entirely. While the actual content of the indentations wasn't particularly damning, the fact that he was trading secret messages instantly tipped them off that he'd been throwing up smokescreen misdirections, a red flag that he actually was Kira.

* Subverted in ''Film/TheBigLebowski'': The Dude uses this trick to see what the pornographer Jackie Treehorn wrote while taking a phone call, but it turns out to be just a doodle of a man with a giant penis.

* ''Film/TheFourthProtocol'' is about a Soviet plot to detonate a nuclear device on British soil and MakeItLookLikeAnAccident. As such an act violates a secret protocol between the nuclear powers, various people get bumped off because [[YouKnowTooMuch They Know Too Much]]. A female military scientist is sent to assemble the bomb that the KGB agent played by Pierce Brosnan will detonate. She delivers a message which Brosnan decodes using a one-time pad, then he burns the message claiming that it just confirms her instructions re setting off the bomb. She ends up sleeping with him, and the morning after rolls over in bed and sees the imprint on the notepad: KILL HER. Brosnan immediately shoves a pillow against her chest and fires his gun through it.

* In the {{novelization}} of ''VideoGame/GabrielKnight: Sins of the Fathers'', when Gabriel discovers that [[spoiler:Professor Hartridge]] is dead, he also finds that the office has been picked clean of evidence, including some notes [[spoiler:the professor]] had been working on to help Gabriel. Fortunately there's enough indentation left in the sheets underneath the removed notes that Gabriel is able to use a pencil to employ this trope to find out what [[spoiler:the professor]] had written anyway. (In the game itself, Gabriel is able to just take the notes without having to go through all that.)
* Mentioned by Franchise/SherlockHolmes when telling Watson how he got his information as "[[LoveLetterLunacy a fact that has dissolved many a happy marriage]]". However, in this case he uses the blotting paper to obtain the reverse message, as the writer had used a pen.

* Played with in ''Discworld/{{Jingo}}'', part of the City Watch subseries of the ''Literature/{{Discworld}}'' books. Someone had written a note on a pad of paper, but someone else came along and took the next few pages to prevent anyone else using this technique. Vimes addresses the resultant FridgeLogic: Why didn't he just take the whole pad? Because he also wanted Vimes to be curious about the contents of the note.

* An episode of ''Series/{{CSINY}}'' has the motive revealed by this type of clue in the BodyOfTheWeek's notebook. [[spoiler:The victim had discovered a dextroamphetamine abuse epidemic in his high school and was going to blow the whistle on it to ''The New York Times''.]]

She then erases the real goal's lines, leaving visible only the cover story that the girls' SecretSociety is just about moths.

* In the Discovery Channel's miniseries ''Series/{{Manhunt}}'' (about the search for the Unabomber) has a RedHerring with this. One of the early leads is that the words "Call Nathan R." were indented on a document sent from the Unabomber. It turns out that one of the first people handling evidence wrote a Post-It note on top of the letter, so the indentation was not from the bomber.
