The Mystery Guest takes place several years after the events of The Maid, as Molly is promoted to head maid. But when famous recluse author J.D. Grimthorpe dies at a press conference at the hotel, Molly and her maid-in-training Lily are again suspected of the crime. Molly’s childhood provides some clues to the Grimthorpe mystery and a few twists along the way. Molly’s own investigation into the crime eventually leads the police detective to encourage her to consider a new career as a detective as her quirks have her notice things not apparent to others. This was a quick read but Molly’s eccentric behavior does get grating.
