Commander Adam Dalgliesh is asked by a friend, Home Office Minister Sir Paul Berowne, to be aware correspondence of a personal nature he's received. He's not being blackmailed and so there's nothing to investigate per se and he only wants Adam to keep an eye on what's going on. Sir Paul's personal life is somewhat complicated. He lives in the shadow of his late brother Hugo and has little time for his wife Barbara who is having an affair with Stephen Lampart. She is now pregnant but insists that the child is his. He's fed up with it all and decides to chuck it all in....

Sir Paul Berowne gives his latest anonymous letter to Adam Dalgliesh and the next day visits Father Francis Barnes at St. Matthews Church in Paddington, requesting permission to spend one night alone in a spare room at his church. The next day, Sir Paul's body is found by Mrs. Wharton, a church volunteer, his throat slit. There was also a homeless man, Harry Mack, also dead in the room with him.

She is Carole Washburn who tells Dagliesh that Berowne had gone through a religious conversion. She refuses however to disclose anything else about their relationship other than they met at work and were always discreet.

Dalgliesh quickly determines that Berowne had fought with his brother-in-law Dominic Swayne who denies killing him. Dalgliesh is upset to learn...
