This is book number 9 in the Di Tom Thorne series.
In the ninth Tom Thorne novel, never before published in the United States, Thorne investigates a troubling case of conspiracy--a wife who arranges to have her husband murdered. He turns up alive... and other people begin to turn up dead.
A decade ago, Alan Langford's charred remains were discovered in his burnt-out car. His wife Donna was found guilty of conspiracy to murder her husband and sentenced to ten years in prison. But before she is released, Donna receives a nasty shock: an anonymous letter containing a photo of her husband. The man she hates with every fibre of her being--the man she paid to have murdered--seems very much alive and well. But how is it possible that her husband is still alive? Where is he? Who sent the photo, and why?
