The rain hammered relentlessly against the tall, ancient windows of Blackwood Manor while all the guests gathered for their dinner. Lord Ashworth had invited eight strangers to his isolated estate, and none of them knew why they were truly there. At precisely nine o'clock in the evening, a piercing scream echoed through the cold marble halls, silencing every conversation instantly. The butler discovered Lord Ashworth's lifeless body sprawled in the study, a silver letter opener buried deep in his chest. Detective Inspector Claire Morgan arrived two hours later, finding the manor sealed by snow and every single guest hiding something. She knew immediately that the killer still remained inside, waiting patiently among them like a wolf dressed in sheep's clothing. The old clock on the marble mantel ticked ominously as she surveyed the room, counting faces and cataloguing nervous glances. Somewhere in this old house of secrets, a murderer watched her every move and smiled behind a mask of innocence.
