“I beg your pardon,” said Arthur. “I hope I have not unintentionally pained you. I hope you have not lost your father?”

“I can’t well lose what I have never had,” retorted the medical student, with a harsh mocking laugh.

“What you have never had!”

The strange man suddenly caught Arthur’s hand again, suddenly looked once more hard in his face.

“Yes,” he said, with a repetition of the bitter laugh. “You have brought a poor devil back into the world who has no business there. Do I astonish you? Well, I have a fancy of my own for telling you what men in my situation generally keep a secret. I have no name and no father. The merciful law of society tells me I am nobody’s son! Ask your father if he will be my father too, and help me on in life with the family name.”

Arthur looked at me more puzzled than ever.

I signed to him to say nothing, and then laid my fingers again on the man’s wrist. No. In spite of the extraordinary speech that he had just made, he was not, as I had been disposed to suspect, beginning to get light-headed. His pulse, by this time, had fallen back to a quiet, slow beat, and his skin was moist and cool. Not a symptom of fever or agitation about him.

Finding that neither of us answered him, he turned to me, and began talking of the extraordinary nature of his case, and asking my advice about the future course of medical treatment to which he ought to subject himself. I said the matter required careful thinking over, and suggested that I should send him a prescription a little later. He told me to write it at once, as he would most likely be leaving Doncaster in the morning before I was up. It was quite useless to represent to him the folly and danger of such a proceeding as this. He heard me politely and patiently, but held to his resolution, without offering any reasons or explanations, and repeated to me that, if I wished to give him a chance of seeing my prescription, I must write it at once.

Hearing this, Arthur volunteered the loan of a traveling writing-case, which he said he had with him, and, bringing it to the bed, shook the note-paper out of the pocket of the case forthwith in his usual careless way. With the paper there fell out on the counterpane of the bed a small packet of sticking-plaster, and a little water-color drawing of a landscape.

The medical student took up the drawing and looked at it. His eye fell on some initials neatly written in cipher in one corner. He started and trembled; his pale face grew whiter than ever; his wild black eyes turned on Arthur, and looked through and through him.
