The rain hammered the old manor windows all night long. Detective Mara Quinn arrived before dawn at the silent house. She found the library door unlocked and the lights burning. Lord Ashworth lay motionless beside his overturned mahogany desk, dead. No servants admitted seeing visitors after ten o'clock that night. His valuable watch still ticked steadily upon his cold wrist. A single shattered teacup rested near the fireplace, stained dark. Mara noticed footprints crossing the dusty floor toward the window. Someone had searched frantically for something hidden inside the desk. She turned slowly, sensing that the killer still remained inside.
