The old manor's library smelled of dust and rain as Detective Marlowe stepped over the shattered lock without a sound. A single brass lamp still burned on the mahogany desk, casting long shadows across the dead man's pale upturned face. The victim's right hand clutched a torn page from a diary, its ink smeared by blood and rain still wet. Marlowe knelt beside the body, careful not to disturb the faint footprints pressed into the damp carpet near the window. He recognized the dead man as Lord Ashworth, the very host who had summoned him here at midnight without explanation. Now a cold draft moved through the broken window, making the lamp flame flicker and the torn page tremble slightly. Now Marlowe read the smeared words aloud, his voice steady despite the chill crawling up his spine like cold fingers. The page bore only five words, written in a frantic hand that had pressed deep into the paper before death. "The killer is still here," Marlowe whispered, and the lamp went out with a sudden hiss in the complete dark.
