The detective arrived at the old mansion under the cover of darkness after receiving the anonymous call about the murder. Blood stained the floor of the grand library where the victim lay sprawled with a dagger protruding from the chest. A mysterious figure watched from the shadows carefully observing every move the detective made while searching for any possible clues. The storm outside raged fiercely as thunder roared and lightning illuminated the house revealing hidden secrets through sudden bright flashes.
