Come Winter by Evan Hunter, Vintage 1974 1st Print Thriller/Horror Paperback

Sandy, David, and Peter met as bored teenagers vacationing with their parents on a small resort island. The horrific crime they committed five years ago bound them together forever, cursing their friendship in blood and setting them on a path toward nihilism and destruction.

Now in their early 20s, the glamorous and sophisticated trio has come to an exclusive ski resort just days before Christmas to satisfy their appetite for danger and enjoy the physical company of the only human beings they can still tolerate: one another. But an interloper soon finds her way into their closed circle. Mary Margaret is no gullible innocent. She’s smart and mischievous and appears bent on tearing the friends apart. Will Sandy, Peter, and David keep their sinister ménage-à-trois intact, or have they finally met their match? On the steep and icy slopes of Semanee Peak, a dangerous game of cat and mouse comes to a shattering end.
