"But supposing all this turned out as you suggest it might, how could even the best disposed friend do anything to help us?"
"That is for after consideration. Let us first find a friend, and we shall find a way to open communication with him. We have no paper, but we could write the message on a piece of linen and drop it down. As far as we can see, from here, there is nothing to prevent anyone coming up to the foot of the wall below us."
For the next four days, nothing whatever happened. They could see that the white handkerchief at the bars attracted some attention, for people stopped and looked up at it, but continued their way without making any gesture that would seem to show that they interested themselves, in any way, in the matter.
On the fourth day, Desmond, who was at the window, said in a tone of excitement:
"There is a man down there who, after looking fixedly in this direction, is making his way towards us. He does not come straight, but moves about among the houses; but he continues to approach. I can't make out his face yet, but there is something about him that reminds me of Mike; though how he could be here, when we left him in the prison at Harwich, is more than I can say."
O'Neil and O'Sullivan in turn looked through the window. Not being so much accustomed as he was to Mike's figure and walk, they could not recognize in the man, in the dress of a country peasant, the well-set-up soldier who attended on Desmond. Both admitted, however, that in point of figure it might well be the man.
"If it is," Desmond said, "all our difficulties are at an end, and I will wager that we shall be free in three or four days. Now, how are we to communicate with him?"
"I have a piece of paper in my pocket. It is only an old bill, and they threw it down, contemptuously, when they searched me," O'Neil said. "I picked it up again. I hardly know why, except perhaps that the idea occurred to me that, some day, I might get a chance of paying it. But as we have no ink, nor pen, nor charcoal, I don't see how it can benefit us."
He drew the bill from the pocket of his coatee. Desmond took it, and stood looking at it in silence for a minute. Then an idea occurred to him.
"I have it!" he exclaimed, presently. "O'Neil, see if you can get a piece of this gold wire off my facings. I want it five or six inches long, so that when it is doubled up and twisted together, so as to be an inch long, it will be stiff enough for our purpose."
