No Witness But The Moon

Description for NO WITNESS BUT THE MOON by Suzanne Chazin:

On a clear, moonlit night in December, police detective Jimmy Vega races to the scene of a reported home invasion in an upscale New York community. As Vega arrives, he spots a Hispanic man who fits the description of the armed intruder, running from the victim's estate. Vega chases him into the woods. When the suspect refuses to surrender -- and reaches into his pocket -- Vega has only seconds to make a life-or-death decision.

What begins as a tragic mistake takes an even darker turn when Vega uncovers disturbing links between the dead man and his own mother's brutal, unsolved murder. Vega's need for answers propels him back to his old Bronx neighborhood, where he is viewed as a disgraced cop, not a homegrown hero. It also puts him at odds with his girlfriend, Adele Figueroa, head of a local immigrant center, who must weigh her own doubts about his behavior.

When a shocking piece of evidence surfaces, it becomes clear that someone doesn't want Vega to put all the pieces together -- and is willing to do whatever it takes to bury the truth. Only by risking everything will Vega be able to find justice, redemption, and the most elusive goal of all: the ability to forgive himself.

This is #3 in A Jimmy Vega Mystery.
