The clock stopped at midnight, though nobody heard it strike. Detective Mara Vale found the body beneath the conservatory stairs. Rain tapped the glass while blood darkened the pale marble. Beside him lay a silver key, warm from someone’s pocket. His watch showed twelve seventeen; the household clock showed eleven. Each guest claimed to have slept alone upstairs that night. Only the dead man seemed to know which clock lied. Vale noticed mud across the carpet, but no footprints leaving. Then the conservatory door clicked open behind her without warning. Someone whispered her name from inside the empty room again.
