The grandfather clock struck midnight. Rain hammered the old mansion. A scream broke the silence. Lord Ashworth lay upon floor. The butler discovered the body. He ran to call police. Inspector Grey arrived within minutes. He noticed the stench immediately. A bloody knife lay nearby. The victim's eyes were wide. Who had committed this crime?
