&;My favorite kind of whodunit, kept me guessing all the way through, and reminiscent of Agatha Christie at her best -- with an extra dose of acid.&; -- Alex Michaelides, author of the #1 New York Times bestseller The Silent Patient Everyone's invited...everyone's a suspect...For fans of Ruth Ware and Tana French, a shivery, atmospheric, page-turning novel of psychological suspense in the tradition of Agatha Christie, in which a group of old college friends are snowed in at a hunting lodge . . . and murder and mayhem ensue.All of them are friends. One of them is a killer.During the languid days of the Christmas break, a group of thirtysomething friends from Oxford meet to welcome in the New Year together, a tradition they began as students ten years ago. For this vacation, they&;ve chosen an idyllic and isolated estate in the Scottish Highlands&;the perfect place to get away and unwind by themselves. They arrive on December 30th, just before a historic blizzard seals the lodge off from the outside world.Two days later, on New Year&;s Day, one of them is dead.The trip began innocently enough: admiring the stunning if foreboding scenery, champagne in front of a crackling fire, and reminiscences about the past. But after a decade, the weight of secret resentments has grown too heavy for the group&;s tenuous nostalgia to bear. Amid the boisterous revelry of New Year&;s Eve, the cord holding them together snaps. Now one of them is dead . . . and another of them did it. Keep your friends close, the old adage goes. But just how close is too close?
