Mystery of the Wax Queen — Carolyn Keene

Louise and Jean Dana are thrilled when their uncle telephones them at Starhurst School and asks them to solve a very puzzling and fascinating mystery involving two Wax Queens, one of them alive! Time is of the essence -- the puzzle must be solved during the girls' spring vacation.

Their detective work takes the Danas to a quaint Greenwich Village shop in New York City. Here they meet and are baffled by a sculptress with extrasensory perception. Weird and spooky adventures confront Louise and Jean as they attempt to unravel the mystery of a valuable wax bust of Queen Victoria which suddenly and strangely appears in the sculptress' shop, then strangely disappears.

Two young women who frequently change disguises and a man suspected of operating a car winning racket try hard to scare Louise and Jean off the case. How the teenage sister sleuths, with the help of their friends Ken Scott and Chris Barton, find the solution to this tantalizing mystery is revealed in the breath-taking climax.
