Cruel Is the Night — Karo Hamalainen

Prizewinning Finnish author Karo Hämäläinen's English-language debut is a literary homage to Agatha Christie and a black comedy locked-room mystery about murder, mayhem, and morality in our cynical modern world.

Three cell phones ring in an opulent London apartment. The calls go unanswered because their recipients are all dead.

Earlier that night, four Finnish friends meet for dinner. It's been ten years since the host, Robert, has seen his once-best friend, Mikko. The two had an ideological falling-out because Robert, a banker, made millions off of unethical (but not illegal) interest rate manipulations. Mikko, meanwhile, is an investigative journalist who has dedicated his career to bringing down corrupt financiers and politicians. Also along for the evening are Mikko's wife, Veera -- with whom Robert once had a secret affair -- and Robert's young trophy wife, Elise. Mikko has arrived in London with an agenda and thinks he's about to get away with murder, but he has no idea what's on the menu for the night: not only does every diner have a bone to pick with another, but there's an arsenal of deadly weapons hiding in plain
sight.

And by the end of the night, there will be only one survivor.
