“No,” I said gravely, if with a smile, “you cannot be expected to understand.”

His clean-shaven lip quivered ever so little before he said, as if wickedly amused—­

“But haven’t you heard just now?  I was thanked by that young lady for understanding so well.”

I looked at him rather hard.  Was there a hidden and inexplicable sneer in this retort?  No.  It was not that.  It might have been resentment.  Yes.  But what had he to resent?  He looked as though he had not slept very well of late.  I could almost feel on me the weight of his unrefreshed, motionless stare, the stare of a man who lies unwinking in the dark, angrily passive in the toils of disastrous thoughts.  Now, when I know how true it was, I can honestly affirm that this was the effect he produced on me.  It was painful in a curiously indefinite way—­for, of course, the definition comes to me now while I sit writing in the fullness of my knowledge.  But this is what the effect was at that time of absolute ignorance.  This new sort of uneasiness which he seemed to be forcing upon me I attempted to put down by assuming a conversational, easy familiarity.

“That extremely charming and essentially admirable young girl (I am—­as you see—­old enough to be frank in my expressions) was referring to her own feelings.  Surely you must have understood that much?”

He made such a brusque movement that he even tottered a little.

“Must understand this!  Not expected to understand that!  I may have other things to do.  And the girl is charming and admirable.  Well—­and if she is!  I suppose I can see that for myself.”

This sally would have been insulting if his voice had not been practically extinct, dried up in his throat; and the rustling effort of his speech too painful to give real offence.

I remained silent, checked between the obvious fact and the subtle impression.  It was open to me to leave him there and then; but the sense of having been entrusted with a mission, the suggestion of Miss Haldin’s last glance, was strong upon me.  After a moment of reflection I said—­

“Shall we walk together a little?”

He shrugged his shoulders so violently that he tottered again.  I saw it out of the corner of my eye as I moved on, with him at my elbow.  He had fallen back a little and was practically out of my sight, unless I turned my head to look at him.  I did not wish to indispose him still further by an appearance of marked curiosity.  It might have been distasteful to such a young and secret refugee from under the pestilential shadow hiding the true, kindly face of his land.  And the shadow, the attendant of his countrymen, stretching across the middle of Europe, was lying on him too, darkening his figure to my mental vision.  “Without doubt,” I said to myself, “he seems a sombre, even a desperate revolutionist; but he is young, he may be unselfish and humane, capable of compassion, of....”
