A man is shot in Paris; pulled from the river, the police find on him a puzzling list of initials, addresses and dates. When they prove to be a series of unsolved murders, Duval suspects a ring of contract killers. With the last entry only partially legible, he faces a problem - that murder is due to happen the following day. In London, Duval faces a race against time to identify the intended victim before it is too late.
