The stout young man drew back a pace.

"You can't do that sort of thing, you know."

"I know I can't," said George, "but I shall. In this life, my dear sir, we must be prepared for every emergency. We must distinguish between the unusual and the impossible. It would be unusual for a comparative stranger to lean out of a cab window and sock you one, but you appear to have laid your plans on the a.s.sumption that it would be impossible. Let this be a lesson to you!"

"I tell you what it is--"

"The advice I give to every young man starting life is 'Never confuse the unusual with the impossible!' Take the present case, for instance. If you had only realized the possibility of somebody some day busting you on the jaw when you tried to get into a cab, you might have thought out dozens of crafty schemes for dealing with the matter. As it is, you are unprepared. The thing comes on you as a surprise. The whisper flies around the clubs: 'Poor old What's-his-name has been taken unawares. He cannot cope with the situation!'"

The man with the collar-studs made another diagnosis. He was seeing clearer and clearer into the thing every minute.

"Looney!" he decided. "This 'ere one's bin moppin' of it up, and the one in the keb's orf 'is bloomin' onion. That's why 'e 's standin' up instead of settin'. 'E won't set down 'cept you bring 'im a bit o' toast, 'cos he thinks 'e 's a poached egg."

George beamed upon the intelligent fellow.

"Your reasoning is admirable, but--"

He broke off here, not because he had not more to say, but for the reason that the stout young man, now in quite a Berserk frame of mind, made a sudden spring at the cab door and clutched the handle, which he was about to wrench when George acted with all the prompt.i.tude and decision which had marked his behaviour from the start.

It was a situation which called for the nicest judgment. To allow the a.s.sailant free play with the handle or even to wrestle with him for its possession entailed the risk that the door might open and reveal the girl. To bust the young man on the jaw, as promised, on the other hand, was not in George's eyes a practical policy.

Excellent a deterrent as the threat of such a proceeding might be, its actual accomplishment was not to be thought of. Gaols yawn and actions for a.s.sault lie in wait for those who go about the place busting their fellows on the jaw. No. Something swift, something decided and immediate was indicated, but something that stopped short of technical battery.

George brought his hand round with a sweep and knocked the stout young man's silk hat off.

The effect was magical. We all of us have our Achilles heel, and--paradoxically enough--in the case of the stout young man that heel was his hat. Superbly built by the only hatter in London who can construct a silk hat that is a silk hat, and freshly ironed by loving hands but a brief hour before at the only shaving-parlour in London where ironing is ironing and not a brutal attack, it was his pride and joy. To lose it was like losing his trousers. It made him feel insufficiently clad. With a pa.s.sionate cry like that of some wild creature deprived of its young, the erstwhile Berserk released the handle and sprang in pursuit. At the same moment the traffic moved on again.

The last George saw was a group scene with the stout young man in the middle of it. The hat had been popped up into the infield, where it had been caught by the messenger boy. The stout young man was bending over it and stroking it with soothing fingers. It was too far off for anything to be audible, but he seemed to George to be murmuring words of endearment to it. Then, placing it on his head, he darted out into the road and George saw him no more. The audience remained motionless, staring at the spot where the incident had happened. They would continue to do this till the next policeman came along and moved them on.

With a pleasant wave of farewell, in case any of them might be glancing in his direction, George drew in his body and sat down.

The girl in brown had risen from the floor, if she had ever been there, and was now seated composedly at the further end of the cab.

CHAPTER 4.

"Well, that's that!" said George.

"I'm so much obliged," said the girl.

"It was a pleasure," said George.

He was enabled now to get a closer, more leisurely and much more satisfactory view of this distressed damsel than had been his good fortune up to the present. Small details which, when he had first caught sight of her, distance had hidden from his view, now presented themselves. Her eyes, he discovered, which he had supposed brown, were only brown in their general colour-scheme.

They were shot with attractive little flecks of gold, matching perfectly the little streaks gold which the sun, coming out again on one of his flying visits and now shining benignantly once more on the world, revealed in her hair. Her chin was square and determined, but its resoluteness was contradicted by a dimple and by the pleasant good-humour of the mouth; and a further softening of the face was effected by the nose, which seemed to have started out with the intention of being dignified and aristocratic but had defeated its purpose by tilting very slightly at the tip. This was a girl who would take chances, but would take them with a smile and laugh when she lost.

George was but an amateur physiognomist, but he could read what was obvious in the faces he encountered; and the more he looked at this girl, the less he was able to understand the scene which had just occurred. The thing mystified him completely. For all her good-humour, there was an air, a manner, a something capable and defensive, about this girl with which he could not imagine any man venturing to take liberties. The gold-brown eyes, as they met his now, were friendly and smiling, but he could imagine them freezing into a stare baleful enough and haughty enough to quell such a person as the silk-hatted young man with a single glance. Why, then, had that super-fatted individual been able to demoralize her to the extent of flying to the shelter of strange cabs? She was composed enough now, it was true, but it had been quite plain that at the moment when she entered the taxi her nerve had momentarily forsaken her. There were mysteries here, beyond George.

The girl looked steadily at George and George looked steadily at her for the s.p.a.ce of perhaps ten seconds. She seemed to George to be summing him up, weighing him. That the inspection proved satisfactory was shown by the fact that at the end of this period she smiled. Then she laughed, a clear pealing laugh which to George was far more musical than the most popular song-hit he had ever written.

"I suppose you are wondering what it's all about?" she said.

This was precisely what George was wondering most consumedly.

"No, no," he said. "Not at all. It's not my business."

"And of course you're much too well bred to be inquisitive about other people's business?"

"Of course I am. What was it all about?"

"I'm afraid I can't tell you."

"But what am I to say to the cabman?"

"I don't know. What do men usually say to cabmen?"

"I mean he will feel very hurt if I don't give him a full explanation of all this. He stooped from his pedestal to make enquiries just now. Condescension like that deserves some recognition."

"Give him a nice big tip."

George was reminded of his reason for being in the cab.

"I ought to have asked before," he said. "Where can I drive you?"

"Oh, I mustn't steal your cab. Where were you going?"

"I was going back to my hotel. I came out without any money, so I shall have to go there first to get some."

The girl started.

"What's the matter?" asked George.

"I've lost my purse!"

"Good Lord! Had it much in it?"

"Not very much. But enough to buy a ticket home."

"Any use asking where that is?"

"None, I'm afraid."

"I wasn't going to, of course."

"Of course not. That's what I admire so much in you. You aren't inquisitive."

George reflected.

"There's only one thing to be done. You will have to wait in the cab at the hotel, while I go and get some money. Then, if you'll let me, I can lend you what you require."
