Always a Bigger Fish (Arlie Undercover Book 3) by Dani Haviland

Just when you think you’ve nabbed crime’s biggest boss, you realize there’s ALWAYS A BIGGER FISH. Arrested and in prison, the De Luca brothers were no longer a problem for Arlie and the Anchorage Police Department, but whoever's been taking scalps is. When Arlie's forensic specialist's former co-worker from North Carolina comes to visit, the two detectives discover the scalp-seeking bandit they’re looking for in both states is the same person. For fans of The Fairies Saga, you'll remember Detective Billy Burke and his young son, Mac from AYE, I AM A FAIRY and THE GREAT BIG FAIRY. Father and son have come out for a winter vacation, but it seems helping Arlie catch the baddie is the best - and safest - thing for him to do. Enjoy the blending of the two series! Although it's book three, this thriller is fun as a stand-alone. You can always come back for more Arlie with books one, two, four, five, six and seven!
