Slated for Death by Elizabeth J. Duncan
When preparing for a local concert to be held in a closed slate mine, organizer Glenda Roberts is murdered. Spa owner Penny Brannigan agrees to take over the event and finds herself involved in the case when Glenda's mother, Doreen (also Penny's friend), is found dead. Could the crimes be related to Glenda's sister, Rebeccah, selling knock-off products in her market stall, or might they have something to do with the workers in the mines years ago? In this sixth book in the Penny Brannigan series, set in Wales, Duncan writes a mystery that would be a great read-alike for people who enjoy M.C. Beaton.
