The body of old Richard Whitmore lay motionless beneath the grand piano, dark blood pooling across the polished marble floor. Detective Sullivan arrived on scene within minutes, surveying the grim surroundings with cold calculating eyes while trembling guests gathered outside. The mansion's butler claimed he found nothing unusual when checking rooms before the tragic discovery was finally reported to police. Every single guest who attended last night's elegant masquerade ball had motive, means, and opportunity to commit this horrific murder. The murder weapon turned out to be an ornate letter opener recovered from beneath the victim's formal evening silk jacket. Among the suspects stood the victim's jealous wife who openly despised his constant late night business meetings far from home. The family's youngest son had recently been cut out of his father's enormous and controversial last will entirely without warning. Strange footprints leading through the garden suggested someone had entered through the unlocked conservatory door during the evening's wild storm. Detective Sullivan knew this case would prove far more difficult than any investigation he had ever encountered in his career. He began questioning each household member individually, carefully watching for the slightest sign of guilt or any concealed dark secrets.
