Rain tapped against frosted glass. The body sprawled on marble. A single rose lay nearby. Its petals were deep crimson. Detective Vance adjusted his collar. He knelt beside the corpse. The room smelled of jasmine. A locked door stood guard. No weapon could be found. Only a small silver key. It glinted in pale moonlight. Vance picked it up carefully. The mystery had just begun.
