They thanked him and took their leave, then repaired to Forsby's bungalow, where they again mulled over the shattering event of the day without getting any further. After a wash and brush up, they dined with Sir Charles, who at first found it difficult to believe what they were saying; but Forsby had brought along a copy of Otto's statement and, after the scientist had read it, he had to agree that the psychic bond between the twins must be accepted.

At half past ten they looked in on Otto. He had tried for an hour before dinner to get into touch with Lothar, then dined in the Mess and, since, tried again, but on both occasions without success. Forsby set the tape recorder in the hope that it might pick up a conversation between the twins during the night, then they all turned in.

On Monday morning the tape proved blank, but Otto reported that he had woken at about half past six after a vivid dream. In it he had seen Lothar getting into an aircraft, standing near which were a number of men in uniform, and he felt sure that these were Americans. He also had a feeling that the place was one of the air bases occupied by United States Forces in Eastern England.

Verney at once rang through to the Air Ministry and asked the senior officer in the Security Department there to take the matter up with his American opposite number and ask for exhaustive enquiries to be made.

This first earnest that Otto might succeed in helping them to trace his brother decided C.B. to take him to London, so that if he had further visions he could give full particulars of them with a minimum of delay. While the aircraft was being got ready to fly them back to Farnborough, Otto arranged with his number two to carry on with the experiments on which he was engaged, then Forsby ran the three of them along to the airstrip.

At Farnborough, Verney's car was waiting to meet them. On the way into central London they stopped at the little hotel in Chelsea and arrangements were made for Otto to stay there, then C.B. dropped Barney in Warwick Square and went on to his office.

In spite of his preoccupations over the week-end, Barney had several times thought of Mary, and he feared that she might have taken rather badly his having had to let her down on Saturday night. So the first thing he did on getting into his flat, was to ring her number. As it was just on lunch-time he hoped to catch her in but there was no reply, so he assumed that she was probably out for the day on one of her modelling jobs.
