At last he judged that his time had come; Binney had brought up coffee and left them alone. 'You sit down there and make yourself at home,' said Caffyn genially, thrusting Mark down into a big saddle-bag arm-chair ('where I can see your confounded face,' he added inwardly). 'Try one of these cigars—they're not bad; and now we can talk comfortably. I tell you what I want to talk about,' he said presently, and a queer smile flitted across his face; 'I want to talk about that book of yours. Oh, I know you want to fight shy of it, but I don't care. It isn't often I have a celebrated author to dine with me, and if you didn't wish to hear it talked about you shouldn't have written it, you know. I want you to tell me a few facts I can retail to people on the best authority, don't you know; so you must just make up your mind to conquer that modesty of yours for once, old fellow, and gratify my impertinent curiosity.'

Mark was feeling so much at ease with himself and Caffyn that even this proposition was not very terrible to him just then. 'All right,' he said lazily; 'what do you want to know first?'

'That's right. Well, first, I must tell you I've read the book. I'd like to say how much I was struck by it if I might.'

'I'm very glad you liked it,' said Mark.

'Like it?' echoed Caffyn; 'my dear fellow, I haven't been so moved by anything for years. The thought you've crammed into that book, the learning, the passion and feeling of the thing! I envy you for being able to feel you have produced it all.' ('That ought to fetch him,' he thought.)

'Oh, as for that,' said Mark with a shrug, and left his remark unfinished, but without, as the other noticed, betraying any particular discomposure.

'Do you remember, now,' pursued Caffyn, 'how the central idea first occurred to you?'

But here again he drew a blank, for Mark had long ago found it expedient to concoct a circumstantial account of how and when the central idea had first occurred to him.

'Well, I'll tell you,' he said. 'It shows how oddly these things are brought about. I was walking down Palace Gardens one afternoon....' and he told the history of the conception of 'Illusion' in his best manner, until Caffyn raged internally.

'You brazen humbug!' he thought; 'to sit there and tell that string of lies to me!' When it was finished he remarked, 'Well, that's very interesting; and I have your permission to tell that again, eh?'
