The old mansion stood silently at the end of town. Detective Sarah Morgan arrived just as the clock struck eight. A body lay crumpled beneath the grand oak staircase here. The victim wore an expensive suit stained deep with blood. No one had heard a single sound during the night. Three guests remained in the house when police finally came. Each one claimed they had been sleeping in their rooms. But someone in this house was hiding a dark secret. Sarah knelt beside the body and studied the pale face. She recognized him immediately as the wealthy businessman Richard Cole. His eyes were open wide as if frozen in shock. A broken wine glass rested just inches from his hand. The red liquid pooled on the cold white marble floor. Sarah noticed faint scratches running along the length of his neck. This was no accident and she knew it right away.
