Devoted In Death by J D Robb

It's a new year in New York city, and two star-crossed lovers have just discovered an insatiable appetite...for murder.

Lieutenant Eve Dallas has witnessed some grisly crimes in her career and she knows just how dark things can get on the streets. But when a much-loved musician is found dead, Eve soon realises that his murder is part of a horrifying killing spree, stretching right across the country.

Now the killers have reached New York, and they've found themselves another victim. Eve knows she only has a couple of days to save a young girl's life, and to stop the killers before their sadistic games escalate. Eve's husband Roarke is ready to put his brains and his considerable resources behind the search. But even as the couple works closely together, time is running out...

There is very little mystery here as you already knows from the start just who the killers are. What brought a fresh prospective to this book was the addition of a Deputy who refuses to just let his case slide and there's even dark cop humour to lighten the mood.

And as usual there as the relationship between Roarke and Eve, "his cop".
