Caffyn felt a keen disappointment, for he had been looking forward to the pleasure of observing the way in which Vincent would take the discovery; but he consoled himself: 'After all, it doesn't matter,' he thought; 'there's only one thing that could start him off like that! What he doesn't know he'll pick up as he goes on. When he knows all, what will he do? Shouldn't wonder if he went straight for Mark. Somehow I'm rather sorry for that poor devil of a Mark—he did me a bad turn once, but I've really almost forgiven him, and—but for Mabel—I think I should have shipped dear Vincent off in perfect ignorance—dear Vincent did bore me so! But I want to be quits with charming, scornful Mabel, and, when she discovers that she's tied for life to a sham, I do think it will make her slightly uncomfortable—especially if I can tell her she's indebted to me for it all! Well, in a day or two there will be an excellent performance of the cottage-act from the "Lady of Lyons" over there, and I only wish I could have got a seat for it. She'll be magnificent. I do pity that miserable beggar, upon my soul, I do—it's some comfort to think that I never did him any harm; he lost me Mabel—and I kept him from losing her. I can tell him that if he tries any reproaches!'

Meanwhile Vincent was spinning along in the dog-cart on his way to Drigg. There had been a fall of snow during the night, and the mountains across the lake seemed grander and more awful, their rugged points showing sharp and black against the blue-tinted snow which lay in the drifts and hollows, and their peaks rising in glittering silver against a pale-blue sky. The air was keen and bracing, and his spirits rose as they drove past the grey-green lake, and through the plantations of bright young larches and sombre fir. He arrived at Drigg in good time for the London train, and, as soon as it stopped at a station of importance, seized the opportunity of procuring a copy of 'Illusion' (one of the earlier editions), which he was fortunate enough to find on the bookstall there. He began to read it at once with a painful interest, for he dreaded lest he had deluded himself in some strange way, but he had not read very far before he became convinced that this was indeed his book—his very own. Here and there, it was true, there were passages which he did not remember having written, some even so obviously foreign to the whole spirit of the book that he grew hot with anger as he read them—but for the most part each line brought back vivid recollections of the very mood and place in which it had been composed. And now he observed something which he had not noticed in first reading the Review—namely, that 'Illusion' was published by the very firm to which he had sent his own manuscript. Had not Mark given him to understand that Chilton and Fladgate had rejected it? How could he reconcile this and the story that the manuscript had afterwards been accidentally destroyed, with the fact of its publication in its present form? And why was the title changed? Who was this Cyril Ernstone, who had dared to interfere with the text? The name seemed to be one he had met before in some connection—but where? Had not Mark shown him long ago a short article of his own which had been published in some magazine over that or some very similar signature? Terrible suspicions flashed across him when these and many other similar circumstances occurred to him. He fought hard against them, however, and succeeded in dismissing them as unworthy of himself and his friend: he shrank from wronging Mark, even in thought, by believing him capable of such treachery as was implied in these doubts. He felt sure of his honour, and that he had only to meet him to receive a perfectly satisfactory explanation of his conduct in the matter, and then Mark and he would hunt down this impostor, Cyril Ernstone, together, and clear up all that was mysterious enough at present. In the meantime he would try to banish it from his mind altogether, and dwell only on the new prospects which had opened so suddenly before him; and in this he found abundant occupation for the remainder of his journey.

He reached Euston too late to do anything that night, and the next morning his first act, even before going in search of Mark, was to drive to Kensington Park Gardens with some faint hope of finding that Mabel had returned. But the windows were blank, and even the front door, as he stood there knocking and ringing repeatedly, had an air of dust and neglect about it which prepared him for the worst. After considerable delay a journeyman plumber unfastened the door and explained that the caretaker had just stepped out, while he himself had been employed on a job with the cistern at the back of the house. He was not able to give Vincent much information. The family were all away; they might be abroad, but he did not know for certain; so Vincent had to leave, with the questions he longed to put unasked. At South Audley Street he was again disappointed. The servant there had not been long in the place, but knew that Mr. Ashburn, the last lodger, had gone away for good, and had left no address, saying he would write or call for his letters. Holroyd could not be at ease until he had satisfied himself that his friend had been true to him. He almost hated himself for feeling any doubt on the subject, and yet Mark had certainly behaved very strangely; in any case he must try to find out who this Cyril Ernstone might be, and he went on to the City and called at Messrs. Chilton and Fladgate's offices with that intention.

Mr. Fladgate himself came down to receive him in the little room in which Mark Ashburn had once waited. 'You wished to speak to me?' he began.

'You have published a book called "Illusion,"' said Vincent, going straight to the point in his impatience. 'I want to know if you feel at liberty to give me any information as to its author?' Mr. Fladgate's eyebrows went up, and the vertical fold between them deepened.

'Information,' he repeated. 'Oh, dear me, no; it is not our practice, really. But you can put your question of course, if you like, and I will tell you if we should be justified in answering you,' he added, as he saw nothing offensive in his visitor's manner.

'Thank you,' said Vincent. 'I will, then. Would you be justified in telling me if the name of "Cyril Ernstone" is a real or assumed one?'

'A few days ago I should have said certainly not; as it is—I presume you are anxious to meet Mr. Ernstone?'

'I am,' said Vincent: 'very much so.'

'Ah, just so; well, it happens that you need not have given yourself the trouble to come here to ask that question. As you are here, however, I can gratify your curiosity without the slightest breach of confidence. There is our later edition of the book on that table; the title-page will tell you all you want to know.'
