A hardened New York cop risks everything to solve an impossible murder The precinct house at 19 Elizabeth Street is one of the oldest in New York, and some things about it never change. Overworked cops interrogate suspects, complain about their wives, and peck out reports on battered old typewriters. Steel mesh covers the windows and the garbage cans overflow. And as Lt. Dan Malone climbs the steps, nursing a hangover, he's certain that no matter what the city throws at them, the men in his squad will be able to handle it. When a naked corpse is found in a bathtub, Malone expects another routine homicide, but this body has stories to tell. Investigating the tragic life and death of Sara Eisinger leads Malone into the thick of an international conspiracy involving the CIA, the Mossad, and a plot to wreak havoc across New York. Only a seasoned cop can solve this mystery, and there's no cop in New York as tough as Lieutenant Malone.

A double murder leads a cop into the darkest corners of the NYPD In Greenpoint, everyone comes to Yetta's.

Joe Gallagher comes by to drop off a birthday cake for Yetta, he doesn't notice the homeless man standing outside. Gallagher has just handed over the cake when the man enters, drops his shopping bag, and pulls out a shotgun. The lieutenant doesn't have time to reach his revolver before he's blown away. Yetta is the next to die. Investigating the double homicide, Det. Lt. Tony Scanlon discovers that Gallagher was more than an ordinary hard-drinking, hardworking Irish cop. And as more killings follow, Scanlon knows that this will be a summer of blood for the NYPD.

A massacre at a Greek resort leads to an unlikely transatlantic partnership On a long overdue vacation, Maj. Andreas Vassos takes his family from Athens to a resort village on the Grecian coast, hoping for sun, surf, and a few days without worry.

And finding the killers and saving the relic takes Vassos to New York City, where he forms a partnership with the NYPD's Teddy Lucas, a Greek immigrant once known as Theodorous Loucopolous. They may not speak the same language, but cops are cops, and either of these men would lay down his life to save his brother in blue.

An undercover cop does all he can to survive as killers close in A hotel maid enters the empty room, changes the towels, and takes the painting off the wall. Stealthily, she replaces it with an identical picture, different only in that it contains sophisticated audiovisual equipment that transmits to the next room. There, two men watch on a monitor and unpack a pair of Uzis. They are backup for a pair of undercover cops who have spent the last ten months infiltrating the city's most powerful drug ring. But when the bullets start to fly, backup won't be enough. The bungled operation leaves three cops dead and the NYPD's undercover network in shambles. As the group tries to pick up the pieces, it falls to deep-cover operative Alejandro Monahan to put things right. After years covertly infiltrating the Cleopatra network of drug smugglers, Monahan understands the unlimited reach of the cartels better than anyone. But can he escape death's grasp?
