Golden rain lashed against the heavy glass of the study. Lord Blackwood sat frozen in his favorite red leather chair. A silver dagger was buried deep within his still chest. Dark blood dripped slowly onto the expensive Persian silk rug. Detective Vance stepped quietly into the cold, silent crime scene. The grandfather clock near the door struck a lonely midnight. A torn calling card remained clutched in his cold hand. The killer had left a cryptic message written in lipstick. Vance realized that this long night had only just begun.
