When Munich businessman Ben Biller receives a mysterious note on his thirty-eighth birthday demanding that he repent for his sins by committing suicide, he dismisses it as a cruel joke. But when his life begins to unravel—he loses his dog, his girlfriend, his job, and his house in quick succession—he suspects that it’s more than a joke: someone is attempting to systematically destroy him.

Desperate and alienated, he turns to Annelie, his old flame. In the midst of his despair, he realizes that with her, he could rebuild his life again. But just as he sees the light at the end of the tunnel, he discovers that his tormenter isn’t done with him yet. Will he discover who is behind the plot before the psychopath’s suggestion of suicide turns to murder?
