Detective Mara Vance arrived at Blackwood Manor just as the morning fog began to lift slowly from the formal gardens. The housekeeper stood trembling on the front steps, her pale hands stained crimson and her eyes staring blankly at nothing. Inside the library, Lord Ashford lay slumped beneath his desk, a polished silver letter opener buried deep in his chest. Rain had fallen steadily all night, which meant the killer never left the manor and was still hiding among them. Mara pulled on her gloves and walked slowly toward the heavy door, already counting the guests who stayed overnight there. Six names, six alibis, and one killer who believed the violent storm had washed away every single trace of guilt.
