Every Little Crook and Nanny

Evan Hunter was more famous for the books he wrote under the pen name Ed McBain (especially his 87th Precinct series) but he also wrote a handful of intelligent mysteries under his own name. In Every Little Crook and Nanny, a comic caper, the child of a vacationing Italian American family is kidnapped by the mob, leaving it to the nanny to scramble to raise the $50,000 ransom.
