Rain hammered the old courthouse windows as Detective Mara Voss stepped beneath the yellow tape and into the marble lobby. A uniformed officer held the door and nodded toward the east wing where the city's most powerful judge lay dead. The victim's chambers smelled of lemon polish, cold coffee, and the metallic bite of dark blood from beneath his desk. Mara knelt beside the fallen judge, noted the single precise stab wound, and saw a fresh coffee cup still steaming. The cup bore bright red lipstick but the judge lived alone and his secretary swore no woman had entered today. A small brass key lay under the heavy desk tagged with a room number from the hotel across the street. Mara carefully bagged the key then noticed a faint footprint in the dark carpet leading toward the judge's private balcony. Outside thunder suddenly cracked and a shadow moved behind the balcony glass vanishing before Mara could draw her service weapon. She crossed the room in three strides shoved the glass open and found only rain rooftops and a knotted rope. Behind her the elevator chimed softly and Mara turned to face a nervous pale waiter holding a polished silver tray.
