There was this, there was that, there was the other, but all of them stood the strain of pulling apart, and remained in their separate entities what they had been in the pat-tern of the whole; and Grant was left, as before, with the belief, so strong and so un-reasonable that it amounted to superstition, that the monogrammed brooch in Sorrell's pocket was the key to the whole mystery; that it was shouting its tale at them, only they could not hear. It lay in his desk with the knife now, and the consciousness of it was with him continually. When he had nothing to do for the moment he would take both it and the knife from the drawer and sit there "mooning over them," as the sympathetic Williams reported to his subordinate. They were becoming a fetish with him. There was some connexion between the two — between the offering that Sorrell had made to a woman and the knife that had killed him. He felt that as strongly and distinctly as he felt the sunlight that warmed his hands as he played with the objects on the table. And yet both his own reason and that of others laughed at the idea. What had the brooch to do with the affair! Gerald Lamont had killed Sorrell with a small Italian knife — his grandmother had been Italian, and if he hadn't inherited the knife he had probably inherited the will to use one — after a quarrel in a queue. On his own showing he resented Sorrell's departure from Britain, leaving him jobless and more or less penniless. Sorrell had had the money to pay for his passage, but had not offered it. And on his own showing he had not known that Sorrell had given him any money until two days after the murder. Where did a pearl monogrammed brooch come into that? The little silver-and-enamel knife was a pièce de résistance in the case — a prince of exhibits. It would be photographed, paragraphed, and discussed in every house in England, and the little crack on its boss handle would hang a man. And all the time that pearl brooch, which would not appear in the case at all, glowed a silent and complete refutal of all their puny theories.

It was utterly ridiculous. Grant hated the sight of the thing, and yet he went back again and again to it as a man does to a mocking mistress. He tried "shutting his eyes" — his favourite resort in a difficulty — and either distracted himself with amusement, or buried himself in work for long periods at a time; but always when he opened his eyes again it was the brooch he saw. That had never happened before — that he had opened his eyes again and seen no new angle in a case. It was borne in on him that either he was obsessed or he had reached the last angle in the case — the vital one — and that it told him nothing; it was there for him to read, and he did not know how to.

Suppose, he would think, just suppose that the murder was an emissary's work after all, and not the result of the quarrel in the queue, what type of person would an emissary be? Not one of those nearest the murdered man, certainly. But no one else had had access to the queue except the policeman, the doorkeeper, and Lamont. Or had there been another who had made his escape unnoticed? Raoul Legarde had gone, and Lamont had gone, without attracting notice — the one because the queue was self-absorbed, the other because it was absorbed in the murder. Was it possible that there had been still another? He reminded himself how indifferent to their surroundings the various witnesses had proved them-selves to have been. Not one of them had been able to give an adequate account of the people who had stood next them, with the exception of Raoul Legarde, who was more critical because he was a stranger to En-gland, and an English crowd was still an entertainment to him. To the others it had been no entertainment, and they had not bothered about their neighbours; they had had all the self-absorption of Londoners and habitual queue-goers. It was still possible that some one else had got away without being remembered. And if that were so, what chance was there now of his being captured? What possible clue had they?

The brooch, said his other self, the brooch!

On Friday, Lamont was again brought up at Gowbridge Police Court, and his counsel protested, as Grant had foreseen, about the statement that had been taken from Lamont. Grant had expected him to protest as a matter of form, but it was evident that he was protesting from conviction. He had become aware of the use the Crown might make of Lamont's admission that he had resented Sorrell's departure. The magistrate said that he could see no evidence of coercion on the part of the police. The prisoner had been evidently not only willing but anxious to make a statement. But Lamont's counsel pointed out that his client had been in no mental or physical condition to make such an important statement. He was barely recovered from a bad concussion. He was not in a fit state to…

And so the wordy, futile argument went on, and the two people whom it most concerned — Grant and Lamont — sat bored and weary, waiting till the spate of words should cease and they could depart, the one to his cell and the other to his work and his ever-present problem. Miss Dinmont was in the now crowded court again, and this time there was no doubt of her graciousness to Grant. Her interview with her aunt seemed to have had the strange effect of softening her in every way, and Grant, remembering Mrs. Everett, marvelled. It was only on the way back to the Yard that it occurred to him that her aunt's belief in Lamont had bred in her a hope that had nothing to do with reason or logic, and that it was the hope that had given her that queer unusual charm that was almost radiance. And Grant swore. She might hope that after all Lamont was not guilty, but what would that avail her if he were convicted?

That pearl brooch! What was it saying? Who had had access to the queue? He flung himself into his room and glared out of the window. He would give up the service. He wasn't fit for it. He kept seeing difficulties where others saw none. It was pure proof of incompetence. How Barker must be laughing at him! Well, let him. Barker had about as much imagination as a paving-stone. But then he, Grant, had too much of it for the police force. He would resign. There would be at least two people who would be grateful to him — the two men who hankered most after his job. As for this case, he would think no more of it.

And even as he made the resolution he turned from the window to take the brooch from its drawer yet once again, but was interrupted by the entrance of Barker.

"Well," said his chief, "I hear they're making a fuss about the statement."

"Yes."

"What good do they think that's going to do them?"

"Don't know. Principle, I suppose. And they see a few admissions that we could make use of, I think."

"Oh, well, let them wriggle," Barker said. "They can't wriggle out of the evidence. Statement or no statement, we've got them on toast. Still worrying over the business?"

"No; I've given it up. After this I'm going to believe what I see and know, and not what I feel."

"Splendid!" said Barker. "You keep a rein on your imagination, Grant, and you'll be a great man some day. Once in five years is often enough to have a flair. If you limit it to that, it's likely to be an asset." And he grinned good-naturedly at his subordinate.

A constable appeared in the doorway, and said to Grant, "A lady to see you, sir."

"Who is it?"

"She wouldn't give her name, but she said it was very important."

"All right. Show her in."

Barker made a movement as if to go, but subsided again, and there was silence while the two men waited for the new arrival. Barker was lounging slightly in front of Grant's desk, and Grant was behind it, his left hand caressing the handle of the drawer that sheltered the brooch. Then the door opened, and the constable ushered in the visitor with an official repetition of his announcement, "A lady to see you, sir."
