Cold In Hand [EPUB ebook] 

Two teenage girls are victims of a bloody Valentine’s Day shooting; one survives, the other is less fortunate…It’s one of a rising number of violent incidents in the city, and DI Charlie Resnick, nearing retirement, is hauled back to the front line to help deal with the fallout. But when the dead girl’s father seeks to lay the blame on DI Lynn Kellogg, Resnick’s colleague and lover, the line between personal and professional becomes dangerously blurred. As Lynn, shaken by this very public accusation, is forced to question her part in the teenager’s death, Resnick struggles against those in the force who disapprove of his maverick ways. But when the unimaginable occurs, an emotional Resnick will need all his strength to see justice done.
