The body was found at precisely three in the morning. Rain hammered the windows like accusations from a gray sky. Detective Marsh stood at the doorway, breathing the cold air. The victim was the richest man in town, Mr. Crane. There was no weapon nearby, no wound upon his skin. His eyes remained open, staring at something unseen by us. Someone had poisoned his evening whiskey, it seemed quite certain. The clock ticked onward, indifferent to the silence inside. Three suspects waited downstairs, each with their own dark secrets. Detective Marsh whispered, "This case will break someone's world."
