The Decagon House Murders

One sentence synopsis... Members of a university detective club visit a deserted island which was the site of a quadruple murder-suicide the year before and start being picked off one by one.

Read it if you like... Agatha Christie: the book is loosely based on ‘And Then There Were None'. Fair play detective stories: the answers are there all along if you're paying attention, no stupid twists at the last minute to reveal disappointing murderers. Or cult-classic Japanese mystery fiction: the characters are one dimensional, the writing is sparse, and it's all completely intentional. The book belongs in the shin honkaku genre of Japanese mysteries, a genre defined by the reader's ability to plausibly solve it.

Dream casting... Will Sharpe as Ellery and Yōsuke Kubozuka as Shimada.
