The Dead Man's Touch. The Maintenon Mysteries, #11

The Dead Man's Touch is the eleventh in the Inspector Gilles Maintenon Mystery Series. Still recovering from a fractured skull and temporary amnesia stemming from the Dead Reckoning case, Inspector Gilles Maintenon accepts three cases from the hand of Roger Langeron, head of the Sûreté in Paris. Two are baffling enough, and one seems deceptively simple. This is just the beginning of a complex but ultimately successful investigation by the officers of the Special Homicide Unit, one where truth is mostly lies and there are plenty of surprises.
