Happy never after Book

On a hunch I picked this book out of a bargain bin not knowing what to expect. It turned out this was an easy and entertaining read about a former Atlanta cop named Callahan Garrity, who quit the force and started running a cleaning service with her mother from their house, while doing some private detecting on the side. This is actually the 4th book in the series, but I didn't feel like I missed out on prior history with these characters. Callahan accepts to search for Delores, the long lost sister of one of her acquaintances, who was part of a trio of singers in the sixties, called the Velveteens, who have been offered a chance at a comeback.
I must say that having recently enjoyed "20 Feet from Stardom" the documentary, I fell into the story right away; I better understood how so many female singers and acts were financially taken advantage of in the old days. The case gets more complicated when the trio's star producer is found dead in his pool house and one of the trio is holding the smoking gun, literally.
I liked all the characters in this story; there was an ordinariness about them that spoke to me. They were also quirky and brave. I enjoyed the sense of family and friendship that was at the centre of it all.
I look forward to reading more books in this series.
