From the New York Times Bestselling authors of Ghosts of Honolulu comes their most harrowing true story yet.

It's 1942, and New York City is at war. German U-boats are sinking ships just miles offshore and Washington DC is convinced that waterfront spies are providing intelligence targeting the ships. To thwart the threat, the Office of Naval Intelligence reaches out to those with the most sway along the waterfronts of Brooklyn and Manhattan – the mob. The result will be one of the most successful and controversial operations in NCIS' long history (before it was even called NCIS.)

The Navy's alliance with Charles "Lucky" Luciano and his organization will send New Yorker Tony Marsloe and his fellow ONI officers on an international odyssey that includes conducting secret meetings with legendary criminals, hunting clandestine spy rings operating on U.S. soil and conducting daring undercover missions behind the bloody frontlines of the invasion of Italy.

Alongside towering historic figures like Meyer Lansky and Gen. George Patton, readers will encounter a kaleidoscope of agents and gangsters who not only shaped the war in Italy but the future of international crime itself.
