The lives of three separate people, told as short stories, are apparently unconnected; until they are linked by the evil of the anonymous salesman.
Cain Mitchell is in love with someone. He will do whatever he can to save them, but his obsession leaves him vulnerable, putting them both at risk. Karl Morgan wants to know the answer to everything, only to find that knowledge can be a curse. Marcus Knight is a poor comic, looking for his big break. But he soon realises that the centre of attention is an uncomfortable place to be.
And then there is the anonymous salesman that links them all. He can see the end; he knows when it is coming and he is afraid because he has seen what is waiting for him in the dark. He has no morals, and his self-preservation makes him a very dangerous man. But even he is working for someone.
Be careful what you wish for, because there is always a catch.
A dark and twisting tale that shifts the plot right until the end, when the final motivations of the principal characters are revealed, together with the consequences of their actions.
