4742903
Detective Jameson stared at the piece of paper on his desk, the number scrawled in red ink: 4742903. It was the third such message he'd received this week, each one leading him on a wild goose chase across the city. The first clue had been found at an abandoned warehouse on the outskirts of town, the second at a quaint café in the heart of the city, and now, this latest one was discovered in a nondescript alleyway.
