In the quiet town of Meadowgrove, a murder was averted. The victim, a wealthy merchant, had been found dead. The culprit, or so the authorities thought, was caught. The merchant's body was discovered in his study. A single gunshot wound, not a struggle. The police were baffled. The murder weapon was missing. The merchant's wife was the last one seen with him. She had a motive. An alibi was her only defense. But the truth was hidden. In the dark, a shadow moved. It was the killer's.
