Presently a slight rustling above announced that the Lieutenant was descending. “Well?” Galabin asked anxiously, as the other alighted beside him.
Von Tressen shook his head with a disappointed look. “Nothing to be seen,” he answered. “One can look into the window well enough; only a kind of low screen runs before it, which effectually hides everything but the cornice round the walls of the room. But that it is a room, and that some one is in it, I am certain, for once I saw a shadow move along the wall.”
“You are sure there is no chance of seeing who is there?”
“Positively none at all; that is, from the tree.”
“The screen before the window makes it more suspicious than ever,” Galabin observed thoughtfully.
“Assuredly it does. Especially as it seems, so far as one could make out, a fixed affair.”
“Osbert,” Galabin said suddenly, “we are bound to see what is behind. We must get to the bottom of the mystery. And if we cannot see through the window, we must get a sight from above.”
“Is it possible?” the Lieutenant asked doubtfully, as he surveyed the high massive walls looming black in front of them.
“I think so,” Galabin answered. “I took the liberty of reconnoitring the walls from the wood to-day, as you know, and believe I have discovered a place where at least the attempt to scale them may be made. But where is our inquisitive friend, Herr D’Alquen?”
“No sign of him.”
