Detective Blake arrived at the quiet mansion just after midnight. He found the study door slightly open and creaking slowly. Inside sat a dead man sprawled across the rich carpet. Blood pooled around the body creating a dark sinister circle. A letter lay open on the desk with mysterious clues. The window was open letting cold night air rush in.
