Grosjean reached England in July 1943 and spent ten days being interrogated at the LRC. He reported all details of his German assignment, providing intricate details such as the license plate numbers of vehicles used by collaborators. He was told that if he worked for Britain, he would correspond with the Germans, with the goal of finding spies in Britain, and of giving the Germans false information about British military movements. If he chose not to work for Britain, he would be offered the position of Air Force instructor. Grosjean agreed to act as a double agent for the Security Service (MI5); he was given the code name FIDO and became one of 40 Double-Cross agents, a group which included

With the knowledge of MI5, but not the French, he was also writing coded letters to his handler in Barcelona. In January 1944, he was given permission to fly again. By March, the Germans had become aware that he was working for the British and he wrote that he was "condemned to death". Both his British and French colleagues no longer trusted him. His handler wrote that it was "necessary to ensure that he got no access to operational information of any kind and that he was as far away from the zone of operations as possible."
