Mańkowska's first few weeks in London were choreographed - presumably by the British authorities - exactly as Witkowski had told her. After her "arrest", news of it was carried in a brief item on the late evening BBC news, and she was taken to what one source describes as "the Patriotic School, an enormous red brick building occupied by MI5". Her interrogator introduced himself as Captain Malcolm Scott. The interrogation lasted for four weeks. She was carefully and systematically questioned about the training she had received from German intelligence and about the tasks that she had been assigned by the Germans. At one of the sessions Captain Scott provided two pieces of surprising information of his own: the first was more welcome than the second. Her husband and sons were also in London. Her husband had made his own way to England. Her sons had appeared separately and the British authorities had no idea, at least officially, how they had managed to make the journey. Unofficially it was presumed that they had arrived, somehow, courtesy of German intelligence. It turned out that the head of German intelligence, Wilhelm Canaris, had already given Mańkowska his personal promise that if she went ahead with the mission to England, the boys would be sent to join her. The information that they were already safely in England came as a great relief but it was not, under all the circumstances, a complete surprise. The second piece of information was less welcome than the first but also, perhaps, not totally unsurprising. Scott knew that the German intelligence agencies had tried to obtain her a set of identity documents for her, but they had been unsuccessful. The British authorities had been willing to provide her with a British passport, but the move had been opposed by the London-based Polish government in exile once they found out that she had been sent by the "Muszkieterowie". Scott said that the British authorities had been trying to convince the Polish leaders in London that Mańkowska was an Abwehr (German) agent, but the Poles remained implacably hostile to her presence in England. Because of this Scott urged her to leave London as soon as possible.
