Zanny the Nanny is also a character in a children's book.
"Grade 4-6-- If one set of twins is double trouble, then two sets of twins in one family is double trouble squared, especially when the twins in question have the power to communicate with oneother telepathically. The Starbuck family includes 12-year-old fraternal twins July Burton and Liberty Bell; their younger mirror image siblings, Charlotte and Amalie; the children's mother, herself a twin; her obnoxious sister, Honey; and, lastly, father Putnam Starbuck, who has just become an undersecretary at the U.

This change of jobs and venue takes the twins and their teacher Zanny the Nanny (oh, these names!) to the native turf of their hero, Sherlock Holmes, and a rendezvous with a mysterious spirit voice that has been invading the twins' telepathic turf...
