Cain's Jawbone is a puzzle book written in 1936, detailing 6 murders in 100 pages. However, it is up to the reader to not only figure out who kills who, but also what order the events happen in. With multiple narrators- none explicitly named- it is a seemingly impossible task. In the 90 years since publishing, only 3 people have successfully solved it. A contest started in 2018 to see who could solve it by December of 2022- the winner receives a cash prize of $350. This thesis will detail my process of solving the book, as well as (part) of my proposed solution. In the spirit of fairness for the competition, I will not submit my proposed page order- but I will go into great detail of what I believe happens, as well as who murders who.
