Best-selling mystery author P.D. James's supremely gifted British homicide investigator, Cmdr. Adam Dalgliesh (Roy Marsden), tackles yet another baffling case. Dalgliesh has his hands full when the head of a mental health clinic turns up dead. The ensuing investigation thrusts the indefatigable investigator into a dicey scenario of betrayal, blackmail and, of course, plenty of intrigue.
