The heavy velvet curtains parted slowly to reveal the silent body sprawled across the ornate rug in the study room. Detective Miller stepped forward carefully while his polished boots clicked against the cold marble floor of the grand old mansion. Rain lashed against the tall windows as a distant clap of thunder echoed through the dark halls of the estate. No one in this house was innocent, and he knew that the killer was still hiding somewhere in the shadows.
