Rain hammered the manor windows as the butler discovered Lord Ashford dead beside the shattered library clock at midnight exactly. A silver dagger lay in his back, reflecting candlelight while thunder hid every distant scream from the sleeping village below. Detective Mara Vale arrived soaking wet, noting the locked door, the missing key, and the widow's pale, very composed face. Only one guest had entered since dinner, yet no one remembered seeing a second shadow cross the dark crimson carpet. Then the corpse's hand twitched, revealing a torn scrap of blue lace clutched tight against his cold, waxen, pale palm.
