Detective Jameson stood outside the mansion on a cold morning. A wealthy businessman lay dead on the marble floor inside. Police officers were already canvassing the property with great care. The victim's wife stood nearby, her eyes filled with tears. A group of guests was being questioned by the others. Mrs. Jenkins, a maid, had been the first to find. The body was still warm to the touch, she said. The murder had happened sometime after 10 o'clock last night. Jameson's eyes moved to the victim, a tall man there. A cigar had been clamped between his clenched teeth so.
