Black Velvet. The Erin O'Reilly Mysteries, #1

Erin learned a lot from her partner: stay alert, follow your nose, and once you've got your teeth in them, never let go. It's tough working nights with the NYPD. The crime rate is high, the hours are terrible, and forget about a personal life. So when Officer O'Reilly and her K-9 Rolf switch over to the day shift, things are looking up. She's even able to find time for a new boyfriend. But when the theft of a priceless painting from the Queens Museum leaves a fellow police officer dead, Erin and her four-legged partner find themselves dealing with dangerous criminals, sleazy art dealers, and obstructive detectives in a race to capture the killers...and just maybe bring closure to a 75-year-old crime.
