Robert Ellery? He had left the house soon after ten, saying that he intended to walk back to his room at Chelsea. The inspector had not yet followed his trail; but he now made up his mind to do so, though he had not much faith in the result. Still, here was at least a loose end that needed tying.

When he had made his list and tabulated his information, Inspector Blaikie did not feel that he had greatly advanced in his quest. Not one of the people on the list seemed in the least likely either to have committed the murders, or to have been even an accessory to them. He began to feel that he had not yet got at all on the track of the real criminal, or at least of the second one, if one of the two men had really killed the other. Was it some one quite outside the circle he had been studying, and, if so, how had that outsider got access to the house? He might have slipped in without being noticed, but it did not seem very likely, and it was far more difficult to see how he had slipped out. But, after all, George Brooklyn had got back somehow after 11.30, and, where he had come, so might another. Perhaps some one had slipped in and out by way of the theatre.

So the inspector made up his mind to go over the whole scene again, and, above all, to find out more about the persons with whom he had to deal—their histories and still more their present ways of life: their loves and, above all, their animosities, if they had any. There, he felt, the clue to the mystery was most likely to be found.

Accordingly, on the following morning—the second after the tragedy—Inspector Blaikie presented himself early at the office of Carter Woodman and sent up his card. Sir Vernon was still far too ill to be consulted, and the next thing seemed to be a visit to his lawyer, who, being both confidential adviser and a close relative, would be certain to know most of what there was to be known about the circumstances surrounding the dead men. Woodman had offered all possible assistance, and had himself suggested a call at his office.

The inspector presented his card to an elderly clerk who was presiding in the outer office, and was at once shown in to the principal. Again he was struck, as he had been on the morning before, with the lawyer’s overflowing vitality. At rather over forty-six, Woodman still looked very much the athlete he had been in his younger days, when he had accumulated three Blues at Oxford, and represented England at Rugby football on more than one occasion. He had given up “childish things,” he used to say; but the abundant vigour of the man remained, and stood out strongly against the rather dingy background which successful solicitors seem to regard as an indispensable mark of respectability. Carter Woodman, the inspector knew, had a big practice, and one of good standing. He did all the legal work of the Brooklyn Corporation, and he was perhaps the best known expert on theatrical law in the country.

Woodman greeted the inspector cordially, and shook his hand with a force that made it tingle for some minutes afterwards.

“Well, inspector,” he said, “what progress? Have you got your eye on the scoundrels yet?”

The inspector shook his head. “We are still only at the beginning of the case, I am afraid. I have come here to take advantage of your offer to give me all the help you can.”

“Of course I will. It is indispensable that the terrible business should be thoroughly cleared up. For one thing, I am very much afraid for Sir Vernon; and there certainly would be more chance of his getting over it if we knew exactly what the truth is. Uncertainty is a killing business. He has not been told yet about Mr. George Brooklyn’s death.”

“You will understand that, as it is impossible for me to see Sir Vernon, I shall have to ask you to tell me all you can about any of the family affairs that may have a bearing on the tragedy. As matters stand it is most important that I should know as much as possible about the circumstances of the two dead men. To establish the possible motives for both crimes may be of the greatest value. There is so little to go upon in the facts themselves that I have to look for evidence from outside the immediate events.”
