The fog pressed against the windows of the old mansion like a ghost, silence broke with a scream from above. The detective arrived and found the door unlocked with the hall lit by single lamp casting shadows on the walls. The detective climbed the creaking stairs and entered the master bedroom a body lay floor near bed single bullet wound. The victim's hand still clutched a letter opener with a monogrammed handle, initials H. W. were engraved on silver blade. A single red rose lay on the floor near the victim's outstretched arm, its petals were fresh placed moments ago.
