The heavy velvet curtains parted slowly to reveal the silent body sprawled across the ornate rug in the study room. Detective Miller stepped inside while the cold rain lashed against the tall glass windows of the grand old Victorian estate. A single crimson stain bloomed upon the white silk shirt as shadows stretched long across the polished dark oak floor. No one spoke while the grandfather clock ticked rhythmically in the corner marking the final moments of the deceased man. The silver letter opener lay discarded near the fireplace where a faint smell of bitter almonds lingered in the air.
