Alexander Wilson was born in Dover in 24 October 1893. He was educated at St. Joseph's College, Hong Kong a prestigious public school St Boniface's Catholic College in Plymouth where he played amateur soccer. He served in the Royal Navy at the start of World War I. He was then commissioned in 1915 in the Royal Army Service Corps escorting motor transports and supplies to France. He received disabling injuries to his knee and shrapnel wounds to the left side of his body before being invalided, and received the Silver War Badge. He was in the merchant navy in 1919 serving as a purser on a requisitioned German liner SS Prinzessin, sailing from London to Vancouver via South Africa, China and Japan. In the early 1920s he was actor-manager of a touring repertory company, which was world renowned. In 1925, he went to British India to become Professor of English Literature at Islamia College, the University of Punjab in Lahore (now part of Pakistan). He began writing spy novels while in India and received his first contract for The Mystery of Tunnel 51 from Longmans and Green Co. in 1927. His fictional chief of the British Intelligence Service, Sir Leonard Wallace, first appears in Chapter IX. There is no documentary evidence that Wilson himself had any connections with MI6 (The Secret Intelligence Service), MI5 (The Security Service) IPI (Indian Political Intelligence in London) or the Indian Intelligence Bureau in Delhi at this time. In total, Wilson wrote and published three academic books and 24 novels; he also wrote 4 unpublished manuscripts. The Sir Leonard Wallace character appears closely based on the first 'C' of MI6 Mansfield Smith-Cumming. He died 4 April 1963, after four wives, and a most colourful life.
