"But to-night? Are you sure there is no mistake?"

"Quite sure. We must go at once."

Barbara went quickly into the inner room, and in a few moments returned closely wrapped in an ample cloak.

"Draw the hood down over your head," said Watson. "The less left for prying eyes to see the better. You have the papers signed by Judge Marriott?"

"Yes."

"One word, madam. No one will hinder us in this house. At the door into the street turn to the right. I shall walk close behind you. Do not hurry. Do not stop if anyone should speak to you, and do not answer them. Walk forward as if I had nothing to do with you."

"I understand."

"Pardon, but the hood does not quite hide your hair. Such hair might betray you if we should meet enemies to-night, for I never saw its like."

Barbara readjusted the hood, and wondered if Gilbert Crosby admired her hair as this trooper did.

Watson opened the door, and they went down the passage together. Two men on the top of the stairs stood aside to let them pass; the street door was open, and Barbara turned to the right, walking alone, the soldier close behind her.
