The snow buried Blackthorn Manor. Inside, a clock struck midnight. Then someone began to scream. Detective Mara Voss dropped everything. She found the library locked. The screaming had abruptly stopped. Mara kicked the door open. Its key remained lodged inside. Lord Blackthorn lay beside embers. Blood darkened his white collar. His fingers clutched a photograph. Mara recognized her own face. Tomorrow’s date was written underneath. Outside, footsteps crunched through snow. But every guest remained inside.
