"I don't believe he knew we were here," said Bessie.
"Well, it won't do to take any chances," observed Tom. "However, we were not told to remain under cover, so I suppose we can go out when we like."
"Better wait until we get some word from the major," suggested Jack, who was getting some of his chum's caution.
All decided this was best, and the boys spent the rest of the afternoon in getting their room to rights, Mrs. Gleason and Bessie doing the same in their apartment. Mrs. Gleason had temporarily been relieved from Red Cross work to recuperate, she said, as she had been under a great strain.
Toward evening Major de Trouville, or "Trouville," as he democratically liked to be called, arrived, and when told of the sight in the street of the spy, who turned out to be the same man who was one of the captors of Bessie and her mother, the officer said:
"I am not surprised. In fact I rather looked for that, and it is one reason why I wanted to get you four together so you could see the man at the same time.
"There is now no doubt as to his intentions, and the fact that he was here so soon after you arrived proves that there is a 'leak' somewhere. We suspected as much, and I think I know where it is. It is good information to have. Well, boys, did I surprise you?" he asked, smiling.
"You did, indeed, but it was a pleasant surprise," said Jack.
"But when are we going to be allowed to do something to silence that monster cannon?" asked Tom. "It's pleasant to be here, but we are not forgetting there is work to do."
"Nor would I have you forget," said the major. "A number of persons were killed to-day by fire from the long-range gun. We believe, now, that there are two or three of them, as the shots come at closer intervals. It is imperative that something be done, and so I have brought you orders."
