The clock stopped at midnight, though nobody heard it strike. Detective Mara Vale found the study door locked from within. Beyond it, Sir Alistair lay beside a single overturned wineglass. Rain tapped the windows, hiding footsteps outside in the garden. His pocket watch rested open, its hands fixed at twelve. A thin trail of mud vanished completely beneath the desk. She looked toward the untouched fireplace, then suddenly stopped breathing.
