The rain hammered against the cottage windows while Inspector Cole examined the body lying silent upon cold dark kitchen floorboards. Martha Lane sat frozen beside the telephone, her trembling hands clutching the receiver as though waiting for one final voice. The victim, Edward Hart, was discovered at dawn by his housekeeper, who swore she heard whispering upstairs sometime past midnight. Dr. Ellis knelt nearby, studying the wound carefully while noting the faint smell of almonds drifting from the victim's mouth. Outside, reporters gathered beneath umbrellas, hungry for details while constables searched the garden path for footprints, weapons, and discarded clues. When Cole noticed the locked study door was untouched inside, he realized the murderer never intended to escape at all.
