“What are you—”

The sentence is never finished. Vernet’s foot has pressed the yielding carpet; he clutches the air wildly, and disappears like a clown in a pantomine.

“Now,” whispers Silly Charlie, “off with your fetters, Warburton, and I will guide you out of this place. You are not entirely safe yet.”

Up from the trap comes a yell loud enough to waken the seven sleepers, and suddenly, from without, comes an answering cry.

“It’s Vernet’s men,” says Silly Charlie. “Now, Warburton, your safety depends upon your wind and speed. Come!”


CHAPTER XVII.

A PROMISE TO THE DEAD.

Guided by Silly Charlie, Alan Warburton finds himself hurrying through crooked streets and dismal alleys, for what seems to him an interminable distance. Now they run forward swiftly; now halt suddenly, while Charlie creeps ahead to reconnoiter the ground over which they must go. At last they have passed the Rubicon, and halting at the corner of a wider street than any they have as yet traversed, Alan’s strange guide says,

“You are tolerably safe now, Mr. Warburton; at least you are not likely to be overtaken by Vernet or his men. You are still a long distance from home, however, and possibly the way is unfamiliar. I would pilot you further, but must hurry back to see how Vernet is coming out.”
