The Invisible Code: A Peculiar Crimes Unit Mystery

London’s craftiest and boldest detectives, Arthur Bryant and John May, are back in this deviously twisting mystery of black magic, madness, and secrets hidden in plain sight.   When a young woman is found dead in the pews of St. Bride’s Church—alone and showing no apparent signs of trauma—Arthur Bryant assumes this  case will go to the Peculiar Crimes Unit, an eccentric team tasked with solving London’s most puzzling murders. Yet the city police take over the investigation, and the PCU is given an even more baffling and bewitching assignment.   Called into headquarters by Oskar Kasavian, the head of Home Office security, Bryant and May are shocked to hear that their longtime adversary now desperately needs their help.
