"No one is going to beat my sister and get away with it," he said fiercely when Robert had mildly deplored his action.

"I sympathise with your point of view," Robert said, "but I personally would rather be beaten nightly for a fortnight than have my photograph on the front page of the Ack-Emma. Especially if I was a young girl."

"If you had been beaten every night for a fortnight and no one did anything about it you might be very glad to have your photograph published in any rag if it got you justice," Leslie observed pertinently and brushed past them into the house.

Mrs. Wynn turned to Robert with a small apologetic smile, and Robert, taking advantage of her softened moment, said: "Mrs. Wynn, if it ever occurs to you that anything in that story of Betty's does not ring true, I hope you won't decide that sleeping dogs are best left."

"Don't pin your faith to that hope, Mr. Blair."

"You would let sleeping dogs lie, and the innocent suffer?"

"Oh no; I didn't mean that. I meant the hope of my doubting Betty's story. If I believed her at the beginning I am not likely to doubt her later."

"One never knows. Someday it may occur to you that this or that does not 'fit. You have a naturally analytic mind; it may present you with a piece of subconscious when you least expect it. Something that has puzzled you deep down may refuse to be pushed down any more."

She had walked to the gate with him, and as he spoke the last sentence he turned to take farewell of her. To his surprise something moved behind her eyes at that light remark of his.

So she wasn't certain after all.

Somewhere, in the story, in the circumstances, there was some small thing that left a question in that sober analytical mind of hers.

What was it?

And then, with what he always remembered afterwards as the only perfect sample of telepathic communication in his experience, he paused as he was stepping into his car, and said: "Had she anything in her pockets when she came home?"

"She had only one pocket; the one in her dress."

"And was there anything in it?"

There was the faintest tightening of the muscles round her mouth. "Just a lipstick," she said, evenly.

"A lipstick! She is a little young for that, isn't she?"

"My dear Mr. Blair, they start experimenting with lipstick at the age of ten. As a wet-day amusement it has taken the place of dressing-up in Mother's things."

"Yes, probably; Woolworth is a great benefactor."

She smiled and said goodbye again and moved towards the house as he drove away.

What puzzled her about the lipstick? Robert wondered, as he turned from the uneven surface of Meadowside Lane on to the black smooth surface of the main Aylesbury-London road. Was it just the fact that the fiends at The Franchise should have left it with the girl? Was that what she found odd?

How amazing that the worry in her subconscious mind had communicated itself so instantly to him. He had not known that he was going to say that sentence about the girl's pockets until he heard himself saying it. It would never have occurred to him, left to himself, to wonder what was in the pocket of her frock. It would not occur to him that the frock might have a pocket at all.

So there was a lipstick.

And its presence was something that puzzled Mrs. Wynn.

Well; that was a straw that could be added to the little heap he had collected. To the fact that the girl had a photographic memory. To the fact that her nose had been put out of joint without warning only a month or two ago. To the fact that she was greedy. To the fact that she was bored with school. To the fact that she liked "reality."

To the fact-above all-that no one in that household, not even detached sensible Mrs. Wynn, knew what went on in Betty Kane's mind. It was quite unbelievable that a girl of fifteen who had been the centre of a young man's world could see herself supplanted over-night without reacting violently to the situation. But Betty had been "very nice about it."

Robert found this heartening. It was proof that that candid young face was no guide at all to the person who was Betty Kane.

Robert had decided to kill a great many birds with one stone by spending the night in London.

To begin with, he wanted to have his hand held. And in the circumstances no one would hold his hand to better purpose than his old school friend Kevin Macdermott. What Kevin did not know about crime was probably not so anyhow. And as a well-known defending counsel his knowledge of human nature was extensive, varied, and peculiar.

At the moment the betting was evens whether Macdermott would die of high blood-pressure before he was sixty, or grace the Woolsack when he was seventy. Robert hoped the latter. He was very fond of Kevin.

They had first gravitated towards each other at school because they were both "going in for Law," but they had become and remained friends because they were complementary. To the Irishman, Robert's equanimity was amusing, provocative, and-when he was tired-restful. To Robert, Kevin's Celt flamboyance was exotic and fascinating. It was typical that Robert's ambition was to go back to the little country town and continue life as it was; while Kevin's was to alter everything that was alterable in the Law and to make as much noise as possible in the doing of it.

So far Kevin had not altered much-though he had done his best where some judges' rulings were concerned-but he had made considerable noise in his effortless, slightly malicious, fashion. Already the presence of Kevin Macdermott in a case added fifty per cent to its newspaper value-and a good deal more than that to its cost.

He had married-advantageously but happily-had a pleasant house near Weybridge and three hardy sons, lean and dark and lively like their father. For town purposes he kept a small flat in St. Paul's Churchyard, where, as he pointed out, he "could afford to look down on Queen Anne." And whenever Robert was in town-which was not oftener than Robert could help-they dined together, either at the flat or at the latest place where Kevin had found good claret. Outside the Law, Kevin's interests were show hacks, claret, and the livelier films of Warner Brothers.

Kevin was to be at some Bar dinner tonight, so his secretary had said when Robert had tried to reach him from Milford; but he would be delighted to have a legitimate excuse for dodging the speeches, so would Robert go along to St. Paul's Churchyard after dinner, and wait for him.

That was a good thing; if Kevin came from a dinner he would be relaxed and prepared to settle down for the evening; not restless and with three-quarters of his mind still back in the court-room as he sometimes was.

Meanwhile, he would ring up Grant at Scotland Yard and see if he could spare him some minutes tomorrow morning. He must get it clear in his mind how he stood in relation with Scotland Yard: fellow sufferers, but on opposite sides of the fence.

At the Fortescue, the Edwardian old place in Jermyn Street, where he had stayed ever since he was first allowed to go to London on his own, they greeted him like a nephew and gave him "the room he had last time"; a dim comfortable box with a shoulder-high bed and a buttoned-plush settee; and brought him up a tray on which reposed an out-size brown kitchen teapot, a Georgian silver cream jug, about a pound of sugar lumps in a sixpenny glass dish, a Dresden cup with flowers and little castles, a red-and-gold Worcester plate made for "their Maj's" William IV and his Queen, and a much buckled kitchen knife with a stained brown handle.

Both the tea and the tray refreshed Robert. He went out into the evening streets feeling vaguely hopeful.

His search for the truth about Betty Kane brought him, only half consciously, to the vacant space where that block of flats had been; the spot where both her parents had died in one shattering burst of high explosive. It was a bare neat space, waiting its appointed part in some plan. Nothing was there to show that a building had ever stood on the spot. Round about, the unharmed houses stood with blank smug faces, like mentally deficient children too idiot to have understood the meaning of a disaster. It had passed them by and that was all they knew or cared about.
