Here's a link to the [[http://www.the39clues.com/ the web site]]. Character sheet is [[Characters/The39Clues here]].

* SacrificialLion:
** [[spoiler:William [=McIntyre=]]].
** [[spoiler:In ''Trust No One'', Alistair Oh]].

* ParentalAbandonment: As stated above, [[spoiler:Ian and Natalie. Isabel disowned them.]] Also, Cora Wizard is no longer speaking to her son Jonah, and [[spoiler:Amy and Dan's father is alive, meaning he left them to basically raise themselves for about nine years.]]
** [[spoiler:It is later revealed that the last case isn't true after all, and that Isabel was merely trying to trick Amy and Dan.]]

** ''In Too Deep'': [[spoiler:[[SacrificialLion Irina]] [[CerebusSyndrome dies]].]]
** ''The Viper's Nest'': [[spoiler:[[TomatoInTheMirror Amy and Dan are Madrigals, just like their parents and Grace before them]].]]

* GoofyPrintUnderwear: Dan has Pokemon on his, and Ian has ''pink dollar signs'' of all things on his, even though [[WeAllLiveInAmerica he's from Britian, where the dollar is not used.]] It’s possible he bought them in America.

* WeAllLiveInAmerica: See the GoofyPrintUnderwear entry above.

* VideoWills: How Grace starts the hunt for The 39 Clues.

* TomatoInTheMirror: This should be two living Tomatoes and three dead Tomatoes in the Mirror. ''The Viper's Nest'' has Dan Cahill revealing Cahill's family's branch. It happens to be [[spoiler:Madrigals, a branch known that is TheDreaded. At the end of ''Storm Warning'', it is explained that their notorious reputation is actually due to their secretiveness, and the Madrigals are actually quite peaceful. Their main goal is to unite the all five branches of the Cahill Family.]]

* TwoAliasesOneCharacter: As the series often involves espionage, it's inevitable that this trope comes into play.

* ThereAreNoTherapists: Whoo, boy... It'd be easier to name the characters in this series who ''don't'' have some form of mommy/daddy issues.

* TeethClenchedTeamwork: Occurs whenever alliances are formed between teams. Of special note are the Cahills and the Kabras in book 3, and the Kabras and Irina in books 5 and 6.

* SeriousBusiness: The 39 Clues.
** Although seeing as the prize for finding all 39 is [[spoiler:super strength, intelligence, creativity and strategy skills]] that could grant you world domination... well, the way all the characters take it seriously doesn't seem too farfetched.

* SacrificialLion: [[spoiler:Irina and Lester]].
** Though [[spoiler:Lester]] may be more of a SacrificialLamb, given the fact that he was only around for one book.

* ScrewTheRulesIHaveMoney: Basically every Cahill BUT Amy and Dan
* ScrewTheRulesImDoingWhatsRight: Amy and Dan. (It gets even more so in the SequelSeries.)
* SecretLegacy

* [[spoiler:NoRomanticResolution: Amy and Ian never discuss their feelings or what happened between them in Korea, and [[OneShotCharacter Kurt]] never shows up again after seemingly being set up as Amy's new love interest in the seventh book]].

** A ''huge'' amount of {{Mook}} deaths occur, many with a healthy dose of NightmareFuel.

* StalkingIsLove: In ''Operation Trinity,'' set before the clue hunt, Ian watches Amy on one of the Cahill activity surveillance camera feeds his parents keep before heading to dinner, and it's revealed he knows that it's time for the schools in her city let out. The entire, plot-irrelevant scene seems to have been thrown in solely to please the [[FanPreferredCouple Amy/Ian shippers]].

* [[spoiler:RedemptionEqualsDeath: For Irina]].

* PutOnABus: The Starlings are caught in an explosion rigged by the Holts and end up in the hospital for the next nine books, [[spoiler:but they return in book ten.]]
