The Decagon House Murders
Borrowing its basic plot structure from Agatha Christie's "And Then There Were None" ( Christie's book is directly referenced by some of the characters at several points ) , it tells the story of a group of seven university students who travel to a deserted island that was the scene of a grisly mass murder six months earlier , where events soon turn ominous .
