History Radio / PleasantGreenUniverse

** ''Albion'': A massive, supernaturally created earthquake afflicts one of England's main Ley Lines, Lairre's inscrutable handler Johnson is BrainwashedAndCrazy with nuclear bombs, and Parker gives an object lesson in the joys and occupational hazards of mixing chaos magick and cold war SpyFiction.

** ''Glamis'': After the aforementioned podcaster's ignominious death, Lairre is partnered with the personality-shifting chaos magick practitioner Agent Parker who bears an old grudge against Lairre. Together with their boss, they investigate the disappearance of two American tourists (who are almost certainly more than they seem) in Theatre/MacBeth's famous castle.

* ''[[https://archive.org/details/mythos_202011 Mythos]]'' (2018): A ConspiracyTheorist podcaster investigating the destruction of Pleasant Green is roped into helping the occult government agency known as The Department of Works (particularly their star agent, the ghost of a medieval French nun turned MagiTek super spy Mary Lairre) save England (and maybe the world, if they absolutely must) from a time traveling wizard.

** Numerous mysteries in "The Case of Charles Dexter Ward" are explained once you know [[spoiler: George Shepley and Ezra Weedon are both cultists. For a start, it explains how she got trapped in the tunnels under the trailer park - they were the only two people she told.]]

** ''The Lovecraft Investigations 4'' (coming late 2023): Kennedy Fisher is on a quest to find Pleasant Green and rescue her former co-host and a journalist named Edwin Lillibridge may hold the key. No official title has been announced, but appears to be based on ''The Haunter of the Dark'".

* HellIsThatNoise: The hideous, distorted screams of the Mi-go when they finally show up in their true form give [[Radio/QuietPlease Mike]] a run for her money in terms of radio drama NightmareFuel. Matthew prefaces the episode in which they make their appearance with ''"It's not an easy ride, I'm afraid"'' and boy, he is not kidding.

* TakeThat: Simpson never misses an opportunity to make his disgust for the pro-brexit faction known.

** "Mythos/Glamis/Albion" are ComicFantasy.

* AFormYouAreComfortableWith: In ''Fugue State'' [[spoiler:the Mi-go(?)]] interact with Blake in the form of a woman who sounds exactly like fellow Department agent Parker (although Blake doesn't comment on this, given that ''Mythos'' hadn't been written yet).

* CompositeCharacter: Joseph Curwen (aka. [[spoiler:Ipku-Aya]]) is mostly based on the character of that name from ''Literature/TheCaseOfCharlesDexterWard'', but [[spoiler:his particular method of cheating death]] is closer to that used by Ephraim Waite in ''Literature/TheThingOnTheDoorstep'', albeit with slightly different limitations. (Interestingly, the idea of Curwen being reimagined as [[spoiler:a later incarnation of a much older {{Body Surf}}ing occultist]] also echoes Creator/AlanMoore's portrayal of Waite in ''ComicBook/{{Providence}}''[[note]]although this is a coincidence, as according to Simpson's blog he didn't read the comic until several years later[[/note]].) And "The Shadow Over Innsmouth" reveals that beyond all of that [[spoiler: Ipku Aya is just another name for, or avatar of, Nyarlathotep.]]

* ClosedCircle: As with the original novella, ''Innsmouth'' makes heavy use of this trope, helped along by the Coronavirus pandemic of UsefulNotes/TheNewTwenties.

** Julian Simpson seems to be a big fan of this trope, as it plays a major role yet again in ''Aldrich Kemp'', specifically [spoiler:both of Clara's parents]] were members of a secret infrasound project who had their memories and personalities altered to keep the knowledge from falling into the wrong hands.

* ''[[https://www.bbc.co.uk/programmes/m0014gtv Who Is Aldrich Kemp?]]'' (2022): A spy story featuring a new character first mentioned in the first bonus episode of ''Innsmouth''. Scheduled to debut in February 2022.

* CallBack: In addition to the many explicit connections ''Whisperer in Darkness'' has to earlier Julian Simpson radio dramas, there are many more subtle nods.

* HistoricalCharactersFictionalRelative: A prominent trope in ''The Lovecraft Investigations''. Charles Dexter Ward and his family are said to be distantly related to several prominent figures from occult history, including Cunning Murrel (maybe, see below), George Pickingill and Rudolf von Sebottendorf. Later on, Kennedy Fisher and the Marsh family are revealed to be descendants of the Comte de Saint Germain. Both Kennedy and Charles' great grandfather Godfrey Tillinghast are also meant to be related to two people with the same last names who were involved in a seemingly inconsequential RealLife carriage accident at Niagara Falls in the 1800s.
