The old clock tower struck midnight over quiet Harlow village. Cold rain fell in heavy sheets against the dark windows. Nobody in the sleeping village had noticed the body yet. It lay crumpled near the garden gate of Ashford Manor. Detective Clara Voss received the call at half past twelve. She pulled her coat tight and stepped into the rain. The victim was a man no one seemed to know. He wore a fine dark suit that cost serious money. Clara knelt down and studied the wound on his neck. This was certainly no accident, and she already knew it. Someone in Harlow village had committed a very cold murder. And that someone was standing very close, watching her work.
