The story is set in a typical old-timers’ neighborhood in central Tel Aviv. For several decades, the neighborhood contained a firehouse and an emergency medical center, as well as a colorful open-air market. But one day, the character of the street changes completely: Bulldozers begin tearing down the buildings, which are to be replaced by two modern multistory houses and a paved public square.

A group of sixth-graders living in the neighborhood discovers that, in addition to the construction company's excavations, another private excavation is under way. It transpires that a pair of criminals decided that the noise and commotion in the area provided a one-time opportunity to unearth a mysterious "treasure chest" that was buried under the old firehouse long ago.

The children’s curiosity and courage ultimately lead to the capture of the criminals moments before the chest is found, which in turn solves the mystery.

A second book in this series, named The Magician from Motzkin Boulevard has already been written and a Hebrew-language edition will be published later this year.

96 pages, full-color hardcover with B/W illustrations inside, 15X22 cm
