Fur love or money / Sofie Ryan.

Enhanced descriptions from Syndetics:

Sarah Grayson is taking a break from her bustling secondhand shop in small-town Maine to spend time with a friend and her dog. But their purr-fect visit comes to an end when the dog leads them to a storm cellar on a nearby property, where they discover a dead body. The deceased turns out to be a sticky-fingered financial adviser who swindled millions from investors and who has been presumed dead for almost three years. Unfortunately, suspicion falls on the owner of the property where the body was found - and that owner is a good friend of Charlotte's Angels', the senior citizen sleuths who work out of Sarah's shop. It's all paws on deck, as the Angels are determined to clear his good name. But with a tight-lipped widow, a possibly shifty sister, and a slew of unhappy investors in the mix, the list of murder suspects seems endless. Sarah, Elvis, and the Angels have a lot of webs to untangle before they can catch the culprit.
