Hunting down a paeodophile priest, Carlyle finds himself up against his old adversary, Christian Holyrod. The Mayor of London is responsible for hosting an upcoming visit by the Pope and does not want any more scandals involving the Catholic Church. Carlyle, however, is not prepared to let crimes slide, putting him on a collision course with both the Mayor and the church.
Without his sympathetic boss, Carole Simpson, to protect him, could this be the end of the line for Carlyle?
Never one to fight only one battle at a time, he also has to deal with an armed robbery at an upscale jewellers in Mayfair...and a serious health scare for Helen, his wife.
