Audiobook The Mystery at the Second-Hand Shop written by Anna Grue. In a quiet provincial Danish town, something is afoot. The volunteers of the local second-hand shop keep dying. Since they’re all OAP's, the police can’t see the problem. It’s the inevitable – if unfortunate – circle of life. However, resident busy-body, and force-to-be-reckoned-with, Anne-Maj Mortensen is not so sure.
