Midnight rain drummed against the ancient shutters of Blackwood Manor, where a lone lamp flickered ominously over the empty hallway. Detective Alistair Morse stepped inside, his trench coat soaked, and sensed a lingering perfume of roses mixed with sharp iron. In the parlor, the lifeless body of the duke lay slumped in his favorite leather chair, a crimson stain spreading. A torn letter in his hand hinted a secret rendezvous, while thunder echoed the distant toll of a church bell.
