The Foreign Legion Novels Part B contains the novels Paper Prison, published in 1939, and The Uniform of Glory, published in 1941. Paper Prison is the story of twin fraternal brothers, Mark and Luke Tuyler, and the woman whom they love, Rosanne. Paper Prison is a complex novel, published (and assumed to be written) in the later part of Wren's life. It is more realistic than most of his more famous novels, with its themes of infidelity, divorce, blackmail, and "killing no murder". The Uniform of Glory is a humorous novel which has the subtitle of "being the true story of a free Frenchman's night out". It is the story of Denis Ducros, a legionnaire who is the servant of the Colonel, Louis Rochefort. On the night of a Legion fête day, Denis dons the uniform of the Colonel and cleverly impersonates him out on the town. Denis has a number of adventures pretending to be the Colonel, including giving non-commissioned officers a dreadful time, giving ordinary legionnaires an enjoyable time, helping the Colonel's daughter with her romance, and helping a number of "filles de joie" to escape their environment for the evening.
