The body lay cold on the marble kitchen floor tonight. Detective Miller entered slowly, his shoes echoing in the silence. Blood stained the expensive carpet near the white grand piano. Someone had turned off all the lights except just one. The victim clutched a broken champagne glass in his hand. Miller noticed muddy footprints leading toward the back garden terrace. Wind blew through the open curtains, carrying the winter's chill. A clock struck midnight in the distant hallway just outside. The murder weapon was nowhere to be found here yet. Miller knew this would be his very hardest case ever.
