Meir and Shloimy and their fam­i­lies are invit­ed guests at a cel­e­bra­to­ry din­ner at the Kosher Won­ton Restau­rant in Boston, cel­e­brat­ing the dis­cov­ery of the ​“dia­monds in the bath­house,” the mys­tery which they helped solve in book one of this series, Dou­ble Trou­ble. Meir’s old­er sis­ter, ten-year-old Shi­ra, who is smart and very obser­vant, notices some­thing strange about the mes­sages in the for­tune cook­ie they are giv­en for dessert. The boys are off and run­ning to solve the new mys­tery. Is some­one tam­per­ing with the for­tune cook­ies? Is it a coin­ci­dence? Rob­bers? Espi­onage? Stolen goods? The police, even­tu­al­ly alert­ed by the boys, appear just in time to make the arrests.

The char­ac­ters and their fam­i­lies are well devel­oped. This mys­tery, which is inter­est­ing­ly and well-writ­ten, will keep the read­er’s atten­tion. The use of Yid­dish words, such as negel vass­er and vasikin minyan, and descrip­tion of Jew­ish reli­gious cus­toms observed by the two fam­i­lies, may lim­it the scope of the read­ing audience.

Rec­om­mend­ed for ages 7 – 10.
