There are remarkably few books by P C Wren in the Library: in the Kindle library, essentially just the Beau Geste trilogy; in this library just one title. This is a non-Foreign Legion novel. "IN this new book by Major Wren the adventure and courage are more on the psychological side than on the physical. There is a mystery. more than a touch of horror. a keen study of an odd 14-year-old boy, and as neat a plot as any one could wish, with every tiny thread caught up at the finish and tied in a beautiful knot."
