Rain fell hard on Elmswood. Detective Hale stood near body. Blood pooled beneath the desk. No one heard the shot. Windows were locked from inside. The victim clutched a letter. Hale knelt beside the corpse. Something felt deeply, terribly wrong. He whispered, "This wasn't suicide." The killer was still watching.
