“True,” interposed Eugene, striking sharply and cutting him short at his mistake, “it does not concern me at all to know. I can say Schoolmaster, which is a most respectable title. You are right, Schoolmaster.”

It was not the dullest part of this goad in its galling of Bradley Headstone, that he had made it himself in a moment of incautious anger. He tried to set his lips so as to prevent their quivering, but they quivered fast.

“Mr Eugene Wrayburn,” said the boy, “I want a word with you. I have wanted it so much, that we have looked out your address in the book, and we have been to your office, and we have come from your office here.”

“You have given yourself much trouble, Schoolmaster,” observed Eugene, blowing the feathery ash from his cigar. “I hope it may prove remunerative.”

“And I am glad to speak,” pursued the boy, “in presence of Mr Lightwood, because it was through Mr Lightwood that you ever saw my sister.”

For a mere moment, Wrayburn turned his eyes aside from the school-master to note the effect of the last word on Mortimer, who, standing on the opposite side of the fire, as soon as the word was spoken, turned his face towards the fire and looked down into it.

“Similarly, it was through Mr Lightwood that you ever saw her again, for you were with him on the night when my father was found, and so I found you with her on the next day. Since then, you have seen my sister often. You have seen my sister oftener and oftener. And I want to know why?”

“Was this worth while, Schoolmaster?” murmured Eugene, with the air of a disinterested adviser. “So much trouble for nothing? You should know best, but I think not.”

“I don’t know, Mr Wrayburn,” answered Bradley, with his passion rising, “why you address me—”

“Don’t you?” said Eugene. “Then I won’t.”

He said it so tauntingly in his perfect placidity, that the respectable right-hand clutching the respectable hair-guard of the respectable watch could have wound it round his throat and strangled him with it. Not another word did Eugene deem it worth while to utter, but stood leaning his head upon his hand, smoking, and looking imperturbably at the chafing Bradley Headstone with his clutching right-hand, until Bradley was wellnigh mad.

“Mr Wrayburn,” proceeded the boy, “we not only know this that I have charged upon you, but we know more. It has not yet come to my sister’s knowledge that we have found it out, but we have. We had a plan, Mr Headstone and I, for my sister’s education, and for its being advised and overlooked by Mr Headstone, who is a much more competent authority, whatever you may pretend to think, as you smoke, than you could produce, if you tried. Then, what do we find? What do we find, Mr Lightwood? Why, we find that my sister is already being taught, without our knowing it. We find that while my sister gives an unwilling and cold ear to our schemes for her advantage — I, her brother, and Mr Headstone, the most competent authority, as his certificates would easily prove, that could be produced — she is wilfully and willingly profiting by other schemes. Ay, and taking pains, too, for I know what such pains are. And so does Mr Headstone! Well! Somebody pays for this, is a thought that naturally occurs to us; who pays? We apply ourselves to find out, Mr Lightwood, and we find that your friend, this Mr Eugene Wrayburn, here, pays. Then I ask him what right has he to do it, and what does he mean by it, and how comes he to be taking such a liberty without my consent, when I am raising myself in the scale of society by my own exertions and Mr Headstone’s aid, and have no right to have any darkness cast upon my prospects, or any imputation upon my respectability, through my sister?”
