Mary Downing Hahn is apparently a fairly popular and award-winning author of horror and suspense books for children in the U.S. She specializes in ghost stories. I read Closed for the Season, in which 13-year-old Logan moves with his parents to a new town and meets Arthur. Arthur tells him all the most important things about the small town, including that an elderly woman was murdered in Logan’s house and money was stolen from the local amusement park before that. So the boys set out to solve these unsolved mysteries.
For an adult, the story isn’t very exciting, nor is it really a mystery. It’s a bit of a “Middle Grade Cosy Crime” story. There were no ghosts in this one, so maybe I’ll read another book by this author that has some.
