Caught up in a moment of boyhood competition, William Bellman recklessly aims his slingshot at a rook resting on a branch, killing the bird instantly. 

It is a small but cruel act, and is soon forgotten. 

By the time he is grown, with a wife and children of his own, William seems to have put the whole incident behind him. It was as if he never killed the thing at all. But rooks don’t forget…

Years later, when a stranger mysteriously enters William’s life, his fortunes begin to turn—and the terrible and unforeseen consequences of his past indiscretion take root. 

In a desperate bid to save the only precious thing he has left, he enters into a rather strange bargain, with an even stranger partner. Together, they found a decidedly macabre business.
