"But he has seen you in that disguise, Dick."
"Yes, and there is nothing striking about it. He would have to see my face to recognize me and I shall take care that he does not."
Indeed, Dick had so many ways of changing his expression, that it was quite likely he could deceive the spy even were they to meet face to face. Bob kept behind Dick as they went down the street on the same side as the spy, the young patriot watching the man closely, and at length seeing him go into a wine shop of a rather unsavory reputation. When he disappeared, Dick turned to Bob and said quickly:
"There is another door to this place down the alley. Go there at once and watch for this fellow to come out. He will do so as soon as he recognizes me."
Then Dick waited a moment for Bob to go down the alley, and entered the shop. He saw the spy sitting at a table, and now, having his own expression, was recognized in a moment.
"Good afternoon," he said, as he walked over to the spy, who was unable to repress a start of surprise. "You did not expect to see me here, did you?"
"Who are you?" the other snarled. "I don't know you from a side of sole leather. Why do you speak to me?"
"I am Captain Dick Slater," said Dick, taking a seat opposite the spy. "You escaped me just now and changed your dress and also took off your beard. You had a friend–a short, somewhat stout man. We have taken care of him. You will find my lieutenant at the other door. I see you are looking toward it. I think you had better go out that way. Time presses, and we had better go now."
The spy suddenly arose, started for the door, threw the chair in front of Dick and shouted:
"This boy is a British spy! Hold him while I go for the guard!"
