When Doctor Marsden arrived he went about his work in businesslike fashion. A physician of that day had ample experience with either gunshot or sword wounds, each being plentiful enough to arouse little curiosity respecting their origin. He brusquely turned Armstrong and the sister out of the room, after having requisitioned what materials he needed, and the two stood together in anxious and somewhat embarrassed silence on the landing, within call if either were needed. The girl was the first to speak.

“I fear my brother’s case is more dangerous than you would have me suppose,” she said in tremulous voice.

“Not from the wound,” he answered.

“From what, then?” she asked in surprise.

“I do not know. He has something on his mind. I saw that from the moment he was hurt. He is very brave, and this accident of itself would make little impression on him. My acquaintance with him is but a few hours old, yet I know he is a fearless youth. Are you aware of a mission that takes him to Oxford?”

“I have not the least knowledge of it. I heard no hint of his going, and he said nothing of his journey when we spoke together.”

“He told me he had expected a comrade who had failed him. Cromwell himself gave him a pass for two. He said he was to see the brother of his sweetheart, who is with the King in Oxford.”

“That is very likely. The two were great friends always, even when they took opposite sides in this deplorable contest which is rending our distracted country.”

“There must be more than friendship in this journey, otherwise Cromwell would not have given him such a pass as he holds. Then for an unknown, un-vouched-for man to enter Oxford at this moment is highly perilous, an action not to be undertaken lightly. If he go in disguise, and such a pass be found on him, not all Cromwell’s army could save him. It may be he is commissioned to treat for peace, but that is unlikely. Such proposals should come from the defeated force. Depend upon it, something important hangs on this Oxford excursion, and if anything can be done to relieve his mind regarding it, this will do more toward his speedy recovery than all the leech’s phlebotomy. If I can render service to him in Oxford, I shall be glad to undertake his commission.”

“Do you, then, go to Oxford?” asked the girl innocently, turning her disquiet and disquieting eyes full upon him.
