The rain-slicked cobblestones gleamed under the flickering gaslight. A small crowd gathered outside the locked library door. The rusty iron key lay beside the dead man's hand. Inspector Hargrove knelt to examine the cold, still body. A single playing card rested beneath the victim's limp fingers. The Queen of Spades stared upward, mocking and silent. No one had entered or left since midnight struck. The clock on the mantle had stopped at precisely two. A broken window latch offered the only possible clue. Outside, a black carriage waited without a driver inside.
