"

Justice left Britain again to become a policeman for the League of Nations in the Territory of the Saar Basin (a region of Germany occupied and governed by France and Germany under a League of Nations mandate originating in the Treaty of Versailles). After the Nazis came to power, he fought in the Spanish Civil War on the Republican side. It was here that he first grew his signature trademark bushy beard, which he retained throughout his career. On return to Britain, he joined the Royal Naval Volunteer Reserve, but after sustaining an injury in 1943 (thought to be shrapnel from a German shell), he was pensioned off.
