From the moment ex-police detective Michael McLaren arrives at his friend’s house, he’s plunged into a nightmare of a case. Two men, hanged a year apart, each killed on a Good Friday. A barrister. A solicitor. Related careers. Related by murder. Related motives? Pottery shards, a torn newspaper article, and biscuits are found in each man’s pocket. What do they signify? And the blackmail letters Melanie receives… Are they related to the murders, or are they separate, terrifying in their own way?Professions, calendar date, McLaren’s attack. Could it all be entwined?
