Suspects

Brooklyn. Early June. A man strolls into a candy  store, pulls out a sawed-off shotgun, and blows  away two people: owner Yetta Zimmerman and her  customer, NYPD Lt. Joe Gallagher. Suddenly it is a  very hot summer for Detective Lt. Tony Scanlon.  For this is just the first in a series of brutal,  inexplicable hits that lead Scanlon on a journey  into the nightmare universe that cops and criminals  cohabit . . . and deep into the private tragedies  of his own life . . . then deeper still into his  other life, the job, where he uncovers a  frightening hidden world riddled with suspects in blue.  But it all begins with the opening double murder  and a moment of shock when Scanlon opens that dead  lieutenant's locker . . . .
