A man who claims to be the Devil is trying to kill him after he witnessed a woman killed by an invisible hand. Lightning bolts that strike from a clear sky, at locations across the globe, to kill a series of former astronauts. A group of friends who sold their souls to the Devil as a joke when they were students find their time is up and the Devil has come to collect. Simon Ark, who may have once been an Egyptian Coptic priest, implies that he is 2000 years old, and he has searched for Satan all these years. The introduction is by Gigi Pandian, an heir to the Impossible Crime tradition. She is the Agatha Award winning author of ten mystery novels and more than a dozen locked room mystery short stories.
