A mutilated body discovered in the woods. A murderous plan conceived in the past. A reckoning 70 years in the making. When lawyer Charlie Priest is attacked in his own home by a man searching for information he claims Priest has, he is drawn into a web of corruption that has its roots in the last desperate days of World War II. When his attacker is found murdered the next day, Priest becomes a suspect and the only way to clear his name is to find out about the mysterious House of Mayfly—a secret society that people will kill for. As Priest races to uncover the truth, can he prevent history from repeating itself?
