Cold rain hammered the narrow alley while Detective Chen carefully examined the silent figure sprawled beneath a broken streetlamp tonight. A single playing card rested upon the dead man's chest, its crimson queen smiling coldly beneath the flickering lamplight overhead. Chen noted the missing wallet, the torn sleeve, and the strange smell of roses that clung to his damp coat. Somewhere above the rusty fire escape, a dark window slammed shut, and hurried footsteps vanished into the sleeping city beyond. She quietly pocketed the card, called for backup, and wondered which elegant liar would claim they never knew him well.
