Suspects

A double murder leads a cop into the darkest corners of the NYPD   In Greenpoint, everyone comes to Yetta's. A candy store one block west of McGoldrick Park, it's a neighborhood landmark, the place where Brooklynites come to sip a soda, buy a paper, and argue about gentrification. But when Lt. 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.
