Delany’s Progress [EPUB ebook] 

Delany left the army after becoming seriously injured whilst on active duty in foreign parts. He was repatriated to England and when he was fully recovered, and because of his admiration for the positive actions of a police officer friend, he joined the Constabulary. His new employers soon became aware that he would make an excellent officer and that he was particularly adept at deep undercover work. This book covers some of his, at times death defying, adventures.
