By chance Turner and Jones were on the same voyage of the "Queen Mary" in 1953 and one evening, they sat at the same dinner table. They found much in common and Jones invited Turner to a dinner at his London club. On 15 December 1953 the dinner was arranged, during which one of Jones' friends, Professor Frederick Norman of King's College London, excitedly shouted "Oslo!!". Turner and Norman privately told Jones over after-dinner drinks that Turner had heard from his old German friend, Hans Ferdinand Mayer at the beginning of the war, in a letter written from Oslo. Upon learning of Mayer's background and position at Siemens, Jones decided to open a correspondence with Mayer using Turner as a middleman. Jones and Mayer met at a 1955 radar conference in Munich and had dinner with Turner at Mayer's house. Jones quickly determined that Mayer had written the Oslo Report. They agreed that divulging who had written the Report would serve no purpose and agreed to silence. They continued to exchange letters, with Mayer providing more details about how he wrote it.
