Though accused of murder and arson, young Rob Adwell is innocent, of that his lawyer Daniel Pitt is certain. And when Pitt's scientist friend Miriam fford Croft and her celebrated mentor Sir Barnabas Saltram perform a forensic analysis of the scene, he has his proof the fire was accidental—until Adwell himself is killed in a similar blaze. Could Saltram be wrong? And if so, how many other cases has he compromised? What essential clue did Daniel and Miriam miss—and how many victims will this killer claim before they find him? Named one of the Best Books of 2020 by the Wall Street Journal, this third Edwardian mystery starring Thomas and Charlotte Pitt's son Daniel "is at once a courtroom thriller, a psychological suspense tale, and a novel of manners (with Ms. Perry being especially sharp on class distinctions)."—WSJ
