The Sixth Riddle

How could it happen that in a quiet neighborhood of Tel Aviv, a nine-year-old girl disappeared in broad daylight and no one noticed? And when two years later, on the same day, another girl, also nine years old, went missing, was that a coincidence or a continuation? And why did the police say nothing to the public?

Private detective Josh Shirman is pondering these questions, having taken on the investigation at the request of one of the unfortunate mothers.
