Lawyer Percy Pollack was last seen a week ago. According to his wife, Clara, Percy had gone to a meeting with his business partner, Dr. Gilbert Birkins, but based on the condition of his body, he died just 36-48 hours ago – which leaves five days unaccounted for. When Judge Henry Scott dies of a similar wound, Brackenreid suddenly recognizes the work of a murderer long thought dead – and that he himself might be next on the killer’s list. The case deeply divides Murdoch and Brackenreid, each pursuing their own line of investigation. But, a grisly new development in Pollack’s murder tells Murdoch that he’s been trying to solve this puzzle without all the pieces.
