1946 and Captain Harry Tennant has returned from service to join the intelligence corp to investigate war crimes - the smaller cases. Which was the exact reason that Rose Kearney's letter seeking to determine the whereabouts of her missing in action brother ended up on his desk.
A very readable story and mystery with descriptions of the time.

Captain Harry Tennant has been given the task by British Intelligence of following Joseph Wolff while he is in Riseborough, East Anglia. Tennant watches as Wolff commits suicide by drowning. Tennant investigates further by searching Wolff's hotel room. But he still wants to known more so starts his own unofficial investigation. When you are dealing with British Intelligence nothing is straightforward or even safe
An interesting and well-written story.
