In 1934, English translator Edward Powys Mathers, renowned for his cryptic crosswords, came up with a new puzzle: a 100-page murder mystery entitled “Cain’s Jawbone.”
To solve it, readers must correctly identify all six murderers and their victims, but doing so requires rearranging the book’s pages, which are published out of order. Only three people have ever correctly figured out the answer: two in the 1930s, and one last year.
Then the relatively obscure book became a worldwide sensation after a viral post on the social media app TikTok.
“I decided to take this nearly impossible task as an opportunity to fulfill a lifelong dream and turn my entire bedroom wall into a murder board,” San Francisco TikTok creator Sarah Scannell says in a video posted Nov. 14, which reveals the 8-by-5-foot “murder wall” she created in her bedroom composed of the pencil-annotated 100 pages taped up and connected by string.
Days later, the book sold out at retailers worldwide.
At press time, the TikTok has 4.6 million views, 1 million likes, 36,600 shares and 5,340 comments. On Nov. 18, the publisher of “Cain’s Jawbone,” Unbound, announced a reprint on Twitter, and pointed to the cause of the sales spike: “To all who found us through @saruuuuuuugh’s TikTok, welcome and thank you!”

The TikTok begins with Scannell grabbing “Cain’s Jawbone” from the wood shelves of San Francisco independent bookstore Green Apple Books before revealing the murder wall in her apartment (which is also mine, as I am her roommate).

The book sold out on Amazon within 24 hours of the initial TikTok’s posting, Scannell said. It was relisted the next day with its price doubled and with shipping delays. Presently, it’s listed on the online behemoth as out of print, with limited availability. As of Friday, publisher Unbound surpassed 5,000 open backorders in the U.S., 2,500 in Canada and 3,000 from U.K. book retailer Waterstones alone — its own website sold out of its stock of 600 within 24 hours. Two days after the initial TikTok’s posting, Joey Goodman, who works at Green Apple Books, tweeted at Scannell to let her know that her TikTok “wreaked havoc” on online orders.
