As the brilliantly successful Chief of Operations of the Subversive Operations Executive in Cairo, intrigue, deception, imitation and disguise were the breath of life to Captain James Jensen, D.S.O., R.N. As a Levantine stevedore agitator, he had won the awed respect of the dock-labourers from Alexandretta to Alexandria: as a camel-driver, he had blasphemously out-camel-driven all available Bedouin competition: and no more pathetic beggar had ever exhibited such realistic sores in the bazaars and marketplaces of the East.
