18. No Longer Safe by AJ Waines. Alice is delighted to receive an invitation to stay in a remote cottage with Karen, a long-lost friend from university. But when unexpected guests arrive and a serious crime takes place, Alice doesn't know who to trust anymore. Good but with an ending that leaves you feeling you've been told the wrong punchline to the joke. Almost forgivable, but with something important missing from the end that would have made it a different ending altogether.
