The cab took them back to the flat, at considerable expense, and Psmith requested Mike to make tea, a performance in which he himself was interested purely as a spectator. He had views on the subject of tea-making which he liked to expound from an armchair or sofa, but he never got further than this. Mike, his back throbbing dully from the blow he had received, and feeling more than a little sore all over, prepared the Etna, fetched the milk, and finally produced the finished article.

Psmith sipped meditatively.

'How pleasant,' he said, 'after strife is rest. We shouldn't have appreciated this simple cup of tea had our sensibilities remained unstirred this afternoon. We can now sit at our ease, like warriors after the fray, till the time comes for setting out to Comrade Waller's once more.'

Mike looked up.

'What! You don't mean to say you're going to sweat out to Clapham again?'

'Undoubtedly. Comrade Waller is expecting us to supper.'

'What absolute rot! We can't fag back there.'

'Noblesse oblige. The cry has gone round the Waller household, "Jackson and Psmith are coming to supper," and we cannot disappoint them now. Already the fatted blanc-mange has been killed, and the table creaks beneath what's left of the midday beef. We must be there; besides, don't you want to see how the poor man is? Probably we shall find him in the act of emitting his last breath. I expect he was lynched by the enthusiastic mob.'

'Not much,' grinned Mike. 'They were too busy with us. All right, I'll come if you really want me to, but it's awful rot.'

One of the many things Mike could never understand in Psmith was his fondness for getting into atmospheres that were not his own. He would go out of his way to do this. Mike, like most boys of his age, was never really happy and at his ease except in the presence of those of his own years and class. Psmith, on the contrary, seemed to be bored by them, and infinitely preferred talking to somebody who lived in quite another world. Mike was not a snob. He simply had not the ability to be at his ease with people in another class from his own. He did not know what to talk to them about, unless they were cricket professionals. With them he was never at a loss.

But Psmith was different. He could get on with anyone. He seemed to have the gift of entering into their minds and seeing things from their point of view.

As regarded Mr Waller, Mike liked him personally, and was prepared, as we have seen, to undertake considerable risks in his defence; but he loathed with all his heart and soul the idea of supper at his house. He knew that he would have nothing to say. Whereas Psmith gave him the impression of looking forward to the thing as a treat.

The house where Mr Waller lived was one of a row of semi-detached villas on the north side of the Common. The door was opened to them by their host himself. So far from looking battered and emitting last breaths, he appeared particularly spruce. He had just returned from Church, and was still wearing his gloves and tall hat. He squeaked with surprise when he saw who were standing on the mat.

'Why, dear me, dear me,' he said. 'Here you are! I have been wondering what had happened to you. I was afraid that you might have been seriously hurt. I was afraid those ruffians might have injured you. When last I saw you, you were being--'

'Chivvied,' interposed Psmith, with dignified melancholy. 'Do not let us try to wrap the fact up in pleasant words. We were being chivvied. We were legging it with the infuriated mob at our heels. An ignominious position for a Shropshire Psmith, but, after all, Napoleon did the same.'

'But what happened? I could not see. I only know that quite suddenly the people seemed to stop listening to me, and all gathered round you and Jackson. And then I saw that Jackson was engaged in a fight with a young man.'

'Comrade Jackson, I imagine, having heard a great deal about all men being equal, was anxious to test the theory, and see whether Comrade Bill was as good a man as he was. The experiment was broken off prematurely, but I personally should be inclined to say that Comrade Jackson had a shade the better of the exchanges.'

Mr Waller looked with interest at Mike, who shuffled and felt awkward. He was hoping that Psmith would say nothing about the reason of his engaging Bill in combat. He had an uneasy feeling that Mr Waller's gratitude would be effusive and overpowering, and he did not wish to pose as the brave young hero. There are moments when one does not feel equal to the _role_.

Fortunately, before Mr Waller had time to ask any further questions, the supper-bell sounded, and they went into the dining-room.

Sunday supper, unless done on a large and informal scale, is probably the most depressing meal in existence. There is a chill discomfort in the round of beef, an icy severity about the open jam tart. The blancmange shivers miserably.

Spirituous liquor helps to counteract the influence of these things, and so does exhilarating conversation. Unfortunately, at Mr Waller's table there was neither. The cashier's views on temperance were not merely for the platform; they extended to the home. And the company was not of the exhilarating sort. Besides Psmith and Mike and their host, there were four people present--Comrade Prebble, the orator; a young man of the name of Richards; Mr Waller's niece, answering to the name of Ada, who was engaged to Mr Richards; and Edward.

Edward was Mr Waller's son. He was ten years old, wore a very tight Eton suit, and had the peculiarly loathsome expression which a snub nose sometimes gives to the young.

It would have been plain to the most casual observer that Mr Waller was fond and proud of his son. The cashier was a widower, and after five minutes' acquaintance with Edward, Mike felt strongly that Mrs Waller was the lucky one. Edward sat next............
