Cthulhu Confidential

Face Madness and Corruption… Alone!

Langston Wright is an African-American war veteran and scholar in WW2-era Washington, DC. Vivian Sinclair is The New York Herald’s most determined scoop-hound in 1930s NYC. And Dex Raymond is a hard-boiled private detective with a nose for trouble in 1930s Los Angeles.

Each is a lone investigator, equipped with smarts, fists, and just maybe a code of honor, uncovering their town’s secret truths. But what happens when you scratch the veneer of human malfeasance to reveal an eternal evil—the malign, cosmic indifference of HP Lovecraft’s Cthulhu Mythos?

You get Cthulhu Confidential™.

You get GUMSHOE One-2-One™.

Can’t find an entire game group who can play when you can?

Want an intense head-to-head gaming experience?

Looking for a game to play online which fits superbly with virtual tabletops?

Cthulhu Confidential includes all the rules you need to play GUMSHOE One-2-One, plus a detailed approach to building your own mysteries.

Horror Goes Hardboiled

Cthulhu Confidential™ drops your hero into the noir nightscape of hardboiled-era Los Angeles, New York or Washington DC. Meet powerbrokers and politicians, rub shoulders with Hollywood studio bosses and fiery evangelists. Face narrow-eyed G-Men, bent cops and dangerous crime lords. But beneath it all, under the scrim of all this human endeavour, lives corruption so old and inhuman you’ll need all your courage and resourcefulness to face it.

Cthulhu Confidential™ features three protagonists each in their own setting, with three fully-featured adventure, which serve as a complete model for further mysteries of your creation.

Vivian Sinclair headshot
Fatal Frequencies

In the offices of the New York Herald, Sadie Cane seeks reporter Vivian Sinclair‘s help. Sadie’s fiancé, George Preston, disappeared three days after a murder in his apartment block. Can Viv uncover the truth about George, and will Sadie like what she finds?

Langston Wright
Capitol Colour

Lynette Miller was a riveter. A few weeks ago, she got a new job: hush-hush, and highly paid. She’s a clever and resourceful young woman, and now she’s missing, and her father is heartbroken. Can Langston Wright unweave a web of deceit, face down racist cops, and uncover the deeper conspiracy which endangers the war effort?

Hello Pelgrane,

Does this product require Trail of Cthulhu? Or is it a stand alone product?

Can Cthulhu Confidential be played over a video call? It looks like there are cards that are traded between the players, so I'm guessing no.

Digital copies of the cards are provided with the PDF, so these can be sent electronically if playing remotely.

Does this game actually have any rules for character generation or is it meant to be only played by using the pregenerated ones?

Pelgrane P August 20, 2019 4:24 pm UTC
Hey Panu, the protagonist characters in the book were designed for those settings, so we'd recommend playing them. However, there are full rules for creating your own character in the book.

There are the very general rules on creating a new character. Though the stories are VERY tailored for the pre-gen. You can, of course, adjust the difficulty of some checks, but it will be hard to get a non-investigator investigate the prepared stories, while preparing your own stories is quite tedious and time-consuming.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
