Case of the Phantom Cat [EPUB ebook] 

In Victorian England, a girl finds a mystery in a country manor: “Readers will enjoy sorting through the legitimate clues and red herrings.”—Booklist Twelve-year-old Maisie lives in her grandmother’s big boarding house, but now she and her dog Eddie are invited to join Maisie’s friend Alice and her high-society family on a trip to the country. It’s lovely to get away from the London smog, but there is something strange about the manor where the girls are staying. Odd noises, horrid smells, and sightings of a spectral cat keep them up at night…Has Alice's father rented a haunted house? There must be a logical explanation, and Maisie plans to use her detecting skills to find out what it is! This is another delightful mystery, with line drawings included, from the author of The Case of the Stolen Sixpence, which Publishers Weekly described as “[a] young Nancy Drew adventure by way of Downton Abbey.”
