Rain lashed against the tall glass windows of the old manor while the lightning illuminated the dark and empty hallway. Detective Miller stood silently by the heavy oak door and waited for the local constable to arrive with more news. A single crimson stain blossomed across the white silk rug near the body of the wealthy and very lonely lord. The scent of bitter almonds hung heavily in the cold air as the detective knelt to examine the dead man. Someone had clearly intended for this crime to look like an accident, but the truth remained hidden in the shadows.
