Rain battered the manor windows. At midnight, somebody stopped screaming. Inspector Vale arrived before dawn. The butler wore fresh gloves. His cuffs were stained crimson. “Nobody has entered,” he whispered. Vale glanced toward the staircase. Wet footprints climbed its steps. Upstairs, Lord Ashcombe lay smiling. A needle pierced his throat. His watch still ticked faithfully. The bedroom door stood locked. Its key rested beneath him. Then Vale noticed the portrait. Someone had painted Ashcombe weeping. The paint was still wet. The signature belonged to Vale.
