The storm raged fiercely outside the ancient dark mansion as the elegant guests arrived for the annual charity gala event. Suddenly a bloodcurdling scream pierced the silence of the elegant mansion revealing the dead body of Lord Harrington lying cold. The sharp detective arrived promptly and began questioning the five nervous suspects gathered carefully in the dimly lit drawing room. Clues were scattered around the crime scene including a bloody knife and a torn piece of expensive fabric carefully hidden.
