To say that Mr. Yeudall welcomed the inspector is an inadequate statement. Grant felt that he must have met the man before and have forgotten it. He betrayed none of the curiosity that was usually rampant on a man's face when the inspector followed his card into a room. Grant was to him merely another charming fellow-being, and almost Before he had made his business clear Grant Found himself being led away to lunch. It was so much nicer to talk over a meal, and it was long after one o'clock and if the inspector hadn't eaten since breakfast, he must be famishing. Grant followed his unexpected host meekly enough; he had not yet got his information, and this seemed to be the only way of getting it. Moreover, a detective officer never throws away the chance of making an acquaintance. If Scotland Yard has a motto it is You Never Know.

Over lunch he learned that Mr. Yeudall had never to his knowledge seen the man he was looking for. He knew by sight or personally all the performers at the festival as well as a great number of those merely interested in it. But none tallied exactly with the description Grant furnished.

"If you think he was musical, try Lyons' orchestra or the picture-houses. Their orchestra performers are mostly Londoners."

Grant did not bother to explain that the supposition that the man was musical had arisen through his supposed connexion with the festival. It was easier and pleasanter to let Mr. Yeudall talk. In the afternoon, however, after he had taken farewell of his cheerful host, he did sift the various orchestras in the town, with the lack of success that he had foreseen. He then telephoned to the Yard to find out how Williams had fared in his hunt after the history of the bank-notes, and spoke to Williams himself, who had just come back after a long morning's work. The notes were with the bank just now. Nothing had transpired so far, but they were on a scent, and the bank were working it.

Well, thought Grant, as he hung up the receiver, one end of the tangle seemed to be working out slowly but surely. Nothing left so clear and incontrovertible a history behind it as a Bank of England note. And if he had failed at Nottingham to trace the dead man himself, their discovery of the friend's identity would inevitably lead them to the knowledge of who the dead man was. And from the dead man to the Levantine would be only a step. Still, he was slightly depressed. He had had such a hunch this morning that before night an unexpected piece of information would have set him on the right track that he surveyed his wasted day with something like disgust, and not even the after-effects of the good lunch Mr. Yeudall had given him, nor the rosy afterglow of that gentleman's good will to men, was sufficient to comfort him. At the station he found that he had half an hour to wait for his train, and he betook himself to the lounge of the nearest hotel in the vague hope of picking up unconsidered trifles of information in that most gossipy of all public places. He surveyed the two waiters with a jaundiced eye. One was supercilious and like an overfed pug, and the other was absent-minded and like a dachshund. Grant felt instinctively that help was not in them. But the person who brought him his coffee was a charming middle-aged waitress. Grant's weary soul brightened at the sight of her. In a few minutes he was indulging in a friendly, if disjointed, exchange of generalities, and when she went away temporarily to attend to the wants of some one else she always came back and hovered within speaking distance until the conversation was resumed. Realizing that a verbal description of a man who was not a hunchback or blind or otherwise abnormal would convey nothing to this woman, who saw in one day at least half a dozen men who might have fitted a description of the dead man, Grant contented himself with giving leads which might provoke useful information of a relative sort.

"You're quiet here just now," he said.

Yes, she admitted; this was their quiet time. They had slack times and busy ones. It just happened like that.

Did it depend on the number of people staying in the hotel?

No, not always. But usually it did. The hotel was the same: they had slack times and busy ones.

Was the hotel ever full up?

Yes; it had been full to bursting when the Cooperative came. The whole two hundred rooms. It was the only time she remembered such a crowd in Nottingham.

"When was that?" asked Grant.

"At the beginning of February," she said. "They come twice a year, though."

At the beginning of February!

Where did the Cooperative people come from?

From all over the Midlands.

Not from London?

No, she thought not; but some of them might have.

Grant went to catch his train, revolving the new possibility and not finding it acceptable, though he was not quite sure why. The dead man had not looked that type. If he had been a shop assistant, it had been in a business requiring considerable chic on the part of its employees.

The journey back to town was not a slow and pleasant revolving of sunlit thoughts. The sun had gone, and a grey mist blotted out the lines of the country. It looked flat, dreary, and unwholesome in the wan evening. Here and there a sheet of water gleamed balefully from among the poplars with the flat, unreflecting surface of pewter. Grant devoted himself to the papers and, when he had exhausted them, watched the grey, formless evening flying past, and let his mind play with the problem of the dead man's occupation. There were three other men in the compartment, and their voluble and occasionally vociferous pronouncements on the subject of casings, whatever they might be, distracted and annoyed him unreasonably. A tangle of signal lights, hung isolated and unrelated in their ruby and emerald across the fading daylight, restored his good humour a little. They were a wonder and a revelation, these lights. It was incredible that anything so faery had its invisible support in stout standards and cross bars, and its being in a dynamo. But he was glad when the long roar and rattle over the points proclaimed the end of the journey, and the more robust lights of London hung above him.

As he turned into the Yard he had a queer feeling that the thing he had set out to find was waiting for him here. His hunch had not played him false. That scrap of information that would be the key to the whole of the dead man's story was about to be put into his hand. His steps quickened unconsciously. He could hardly wait. Never had lifts seemed so slow or passages so long.

And after all there was nothing — nothing but the written report which Williams, who had gone to tea, had left for him when he should come in — a more detailed recapitulation of what he had already heard over the telephone.

But at the exact moment that Inspector Grant had turned into the Yard a queer thing had happened to Danny Miller. He had been seated sideways in an easy-chair in an upper room of the house in Pimlico, his neat feet in their exquisite shoes dangling idly from the upholstered arm, and a cigarette in a six-inch holder projecting at an aggressive angle from his thin mouth. Standing in the middle of the floor was his "jape." She was engaged in trying on a series of evening frocks, which she wrested from their cardboard shells as one thumbs peas from a pod. Slowly she turned her beautiful body so that the light caught the beaded surface of the fragile stuff and accentuated the long lines of her figure.

"That's a nice one, isn't it?" she said, her eyes seeking Danny's in the mirror. But even as she looked she saw the eyes, focused on the middle of her back, widen to a wild stare. She swung round. "What's the matter?" she asked. But Danny apparently did not hear her; the focus of his eyes did not alter. Suddenly he snatched the cigarette-holder from his mouth, pitched the cigarette into the fireplace, and sprang to his feet with wild gropings about him.
