Rain hammered empty streets outside detective Marlowe's dim cluttered office. A sharp knock shattered silence just before midnight loudly struck. Evelyn Crane entered soaked, clutching faded wedding photograph tightly silently. My husband is dead, she whispered, voice cold barely trembling. Marlowe studied crimson stains darkening her pale white trembling gloves. Thunder rumbled somewhere distant while clock ticked slowly ominously onward. Someone murdered him at midnight during grand annual masquerade ball. Only Marlowe noticed strange dusty footprint leading toward locked library.
