Watch Over Me - Navajo Code Talkers, #2

At first, war widow Kitty Charente thinks she's showing one of her boss's salesman a day out on the town.  But Luke Kayenta is undercover: he's a Navajo code talker, and Nazi Agent Helmut Adler is hunting him in 1942 New York City.  Isolationists are searching for Luke too.  And his superiors at the the U. S. Office of Strategic Services want to know if he's cracked under torture in Spain. Kitty and Luke must evade capture from one enemy and death from another as they race from the Lower East Side to the Savoy Ballroom to Coney Island, aided by unlikely allies in the Canadian and French spy networks, a Harlem baker, and even Weegee, New York City's most famous tabloid photographer.
