The drowned man : a Peter Cammon mystery
(Book)

Retired Chief Inspector Peter Cammon travels to Canada to retrieve the body of a murdered Scotland Yard colleague who was brutally attacked, run over by a car, and then dumped into a canal -- all seemingly for the theft of three letters from the American Civil War era, one of which is signed by John Wilkes Booth. Meanwhile, Alice Nahri, the girlfriend of the dead man, looms over the investigation.
