Rain fell hard on Marlowe. The old house stood silent. Detective Hale stepped inside slowly. Blood pooled near the fireplace. A woman lay very still. Her eyes stared at nothing. No weapon rested on floor. The clock had stopped ticking. Someone had locked every door. Hale knelt beside the body. Something felt terribly, deeply wrong. This was no simple accident. Somewhere, the killer watched closely.
