The Sassoon Files

Watermarked PDF

Horror in the Pearl of the East! The Sassoon Files is a set of scenarios and campaign resources for Call of Cthulhu 7th Edition and GUMSHOE role-playing games (RPGs) set in historical 1920s Shanghai; an international city of intrigue, espionage, style and violence. 

If you like The Sassoon Files, see the add-on scenario "The Brother of Jesus."


Victor Sassoon, a preeminent bon vivant, has found himself trading correspondence with Doctor Henry Armitage. They share a common goal and a common modus operandi. Victor fights to keep his empire safe, but he also fights for a Shanghai free from Mythos influence. Victor has gathered around him professors, detectives, muscles, guns, criminals and other problem solvers to mount a defense against a rising tide. Victor is your hook.

The trail leads to...

 - a strange gate opened by an ancient Daoist ritual, and an alien spirit called forth from the Polaris solar system.

 - a Shanghai triad operated by someone claiming to be the deceased Empress Dowager Cixi.

 - a scam at the horse track, a heartbroken triad gangster, and the Bloated Woman.

 - a lost city of golden sands, a field of black lotus, and a place suspended in time and space.

The Sassoon Files is 208 file pages long. Modular in design, each of the 4 scenarios may be played as a "one-off" session or as part of a larger campaign set in 1920's Shanghai. The scenarios are tied together by common locations, characters, threats and themes. The history of the Paris of the East is rich; with the help of the Sassoon Files, you are able to dig deep into the vein of Old Shanghai.

The Sassoon Files includes the history of Shanghai and some of the primary factions that competed for influence and power: the Communists and Nationalists who played a game of deadly cat and mouse; the Jewish tycoon who provided succor to refugees; the Triad societies who competed to provide vice for the city's residents; the Japanese who were moving closer to invasion. The Sassoon Files also explores the secret history of the Mythos, and the local factions who sought to exploit that which could not be fully comprehended.

I played the Let Sleeping Dogs Lie part of this at Gen Con 2019. I had fun. Didn't remember the publishers for this until I saw the current Kickstarter Journal d'Indochine so thanks for that now I remember so I am buying this so I can read it. Hope that the rest lives up to my Gen Con experience. :)

Any chance to see this as POD? I live outside US and trying to buy the book from your webpage adds 22$ just for shipping costs...

Bought the book. Wanted the printing version but shipping is way too high so I chose to go with the pdf instead. I live in China (been living here for almost 10 years now) and sucks what happened to this book. I will be running the second scenario soon(ish). Great deal of info in this sourcebook!

The material covered in this book is simply amazing. Very high value indeed, which reflects that a considerable amount of research was done to put this book together. OTOH, I think the authors should have avoided commenting about who was supposedly more popular than who in reference to the Chinese Communist Party, or about who did what during the Cultural Revolution, etc., etc. In other CoC material, we don't get comments concerning the presidents or the senators of the USA, and neither about the Republicans or Democrats, for instance. So I believe that it was a mistake to bring up these issues and publish them in the adventure book. That being said, every Keeper should have this book in his or her collection. A must buy !

Thank you for your kind words.

We developed the Lore Sheet system so as to give packets of information to Investigators, assuming they know nothing about the setting - Shanghai in the 1920s. Many people know the name Mao Zedong, like they know the name Stalin. But having Zhou Enlai as a character is sort of like having Thomas Jefferson as a character in a game, although many people (especially younger players) may not know who Zhou is. So as I (I'm Jesse BTW) wrote the historical settings section, I felt it was important to convey a sense of how these people are remembered by Chinese people.

We stand by you Sons of the Singularity. Chinese censorship was way out of line.

Hey. Sorry for not getting back to your earlier. We do not plan to release The Sassoon Files as POD, however, we are working on making the Brother of Jesus add-on scenario available for POD. The Sassoon Files main book pre-sales order is currently sold on the Sons of the Singularity website, for the next 3-4 weeks or so. The book will be available on that website when the printing is done, in about a month.

Original electronic
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.
