Tony Hale, Space Detective is a juvenile science fiction novel, the fifteenth in Hugh Walters' Chris Godfrey of U.N.E.X.A.
This and all subsequent books in the series focused on either Earth or local planetary adventures, as technology to explore further afield could not be justified by Walters.
A series of unexplained disappearances from Lunar City leads to the assignment of Morrey Kant, Serge Smyslov and Tony Hale to investigate.
Without any leads, Tony Hale devises a bold solo plan and is himself kidnapped.
