The Decagon House Murders (House Murders, #1)

The lonely, rockbound island of Tsunojima is notorious as the site of a series of bloody unsolved murders. Some even say it’s haunted. One thing’s for sure: it’s the perfect destination for the K-University Mystery Club’s annual trip.

But when the first club member turns up dead, the remaining amateur sleuths realise they will need all of their murder-mystery expertise to get off the island alive.

As the party are picked off one by one, the survivors grow desperate and paranoid, turning on each other. Will anyone be able to untangle the murderer’s fiendish plan before it’s too late?
