MR. LAMBTON RECEIVED Superintendent Allenby's report before leaving the House, and it went far to relieve his mind. The American Ambassador had returned to Grosvenor Square with a daughter who had been no more than superficially damaged, and without having involved himself in any further homicidal episodes. International amity seemed unlikely to be disturbed.

So far, good. But there were other aspects of the matter such as might still lead the most cautious Secretary to make one of those blunders which cause the Home Office to be regarded as the most perilous stage of a climbing politician's career.

Allenby ended his report by saying: "Snacklit made himself scarce, knocked about though he certainly was, as soon as our men entered the building. It's difficult to guess how it was done, as we had every exit watched. It looks as though he'd got a getaway planned beforehand, and when he knew we were there he saw that the game was up. Anyway, it was pleading guilty in a loud voice, and he shouldn't take long to catch. Not with his face marked as it is."

Mr. Lambton said he supposed not. What arrests had actually been made?

"Only the man Burfoot. It'll be a long stretch, if not the gallows, for him. We've brought another man named Wilkes in for questioning, but we haven't gone further than that. There are one or two others who won't leave Snacklit House without our having something to say. But I told Sergeant Duckworth to go slow till we'd thought it out."

"Quite right. What about Blinkwell?"

"We've done nothing so far. We've not got much to go on. And I didn't know what you would wish. . . . Of course, there are those extradition papers on the way. We can't ignore them."

"No. They can't be ignored. But there's no need to do more tonight. I'll see Sir Henry in the morning, and talk it over with him."

Mr. Lambton, his mind greatly relieved, though not unaware of further problems ahead, went home for a short night's sleep.

But Allenby had still instructions to give, such as would keep some of his best men busy through the night, and then, before leaving for his own neglected bed, he gave orders that Professor Blinkwell should be rung up at an early hour, with a request to call during the morning at Scotland Yard, "not before ten-thirty, or say ten-forty-five, We ought to know where we are by then." By that time he would have Sir Henry's instructions. He would have spoken to the S?ret? again. It was possible that the extradition papers would be on his desk. . . .

Professor Blinkwell was punctual. It was exactly ten-fortyfour when he stepped out of his car, and he was shown up to Superintendent Allenby's room without delay.

"It was good of you," he said as he entered, "to ring me up. But I should, in any case, have given you a call this morning. It appeared to me that you ought to know just what I saw and heard at Snacklit's House, though I am not sure that it will be of material assistance to your investigations. But that is for you to decide.".

"Yes."

"You will like to have what I say taken down?"

"Sergeant Temple is doing that."

Professor Blinkwell looked at the officer seated at the further end of the room as though he had not observed him before. "It is a good method," he said. "It saves both repetitions and doubt."

"Yes. . . . You know Snacklit?"

"It is a matter of how you use the word. He consulted me some time ago regarding the composition of a gas which he is accustomed to use. At that time he struck me as a humane man."

"When was that?"

"The date may be of importance? It is hard to see how. But in that case I should prefer to consult my diary before I reply."

"Approximately?"

"If you please, I prefer accuracy. I will consult my diary and let you know."

"You might help us materially if you would say what drew your suspicions in his direction?"

For the first time, the Professor showed signs of embarrassment. "I was afraid," he said, "that you would ask that. It was through a private matter, which I should prefer not to explain."

"I am afraid I must press it."

He still hesitated. Kindell, he said at last, is an attractive young man."

"Yes. What of that?"

"And I have a niece who is still young. . . . Miss Thurlow is younger."

"No doubt she is. But I fail to see - - "

"Mr. Kindell had engagements he did not, and perhaps could not, explain. You understand that better than I. Curiosity was aroused."

"You are explaining nothing at all."

"Perhaps jealousy would be a more adequate word."

"Perhaps it might. But I still fail to see - - "

"Is it necessary that you should? What I desired to convey was that curiosity - or jealousy - being aroused, things were noticed - perhaps I should say discovered, which would otherwise - I think I must have made myself sufficiently clear."

"No. I can't say that you have. What I asked was what had first caused you to suspect Snacklit."

"I am afraid that I must decline to be more specific. I may already have said too much. And it is not, in fact, an explanation that could help you at all. What I thought I ought to tell you is what occurred when I reached Snacklit House, a short while before Mr. Thurlow intervened, perhaps more effectually than I should have been able to do."

"You don't mind our questioning Miss Blinkwell?"

"About what I have said? It would be a gaucherie which I should regret. But it would not be within my power to prevent If you would imply that it might disclose some indiscretion of mine - which is absurd - no, I should not object at all."

"Very well. . . . Then we will come to what happened at Snacklit House."

"I saw Mr. Snacklit in the lounge on the first floor. The girl whom I afterwards heard called Kate, showed me up, or, at least would have announced me, but I followed her without waiting for that.

"I found him on the couch, his face very badly cut and discoloured, and my first question was naturally to enquire how he had come to be in such a condition. He said something about a hellcat, or some such word, and I replied that Miss Thurlow would certainly not have committed such an act unless the provocation had been extreme. It was a shot in the dark, but it went home.

"He looked frightened, and, I thought, conscious for the first time of the indiscretion of what he had said before. He said something about not knowing what I meant, and I became seriously alarmed as I considered the kind of scene which must have occurred, and how he could have disposed of her subsequently.

"I told him that I was enquiring for Miss Thurlow, and that, in view of his condition, and what he had said about it already, it was useless to profess ignorance.

"I said that I had no wish to create any disturbance and, in view of the punishment he had received, nothing more might be said about the matter, if he would allow me to take her quietly away.

"He said I could take anyone away as far as he was concerned, but as he didn't know who I was talking about he couldn't say more than that.

"I told him that I must take that as permission to search the house, and he told me to go to hell.

"He gave me the impression of a man who was in such a state of combined mental desperation and physical pain that he was hardly conscious of what he said.

"I left him then, and went down some back stairs, and found myself in a lighted passage. I went along that, and came to a large incinerator built out from the house, and a man was there stoking up."

"You mean Wilkes?"

"I did not have occasion to ask his name."

"We arrested him for murder an hour ago."

"From his appearance and manner I cannot say that it is an incredible charge. But when I told him that I was looking for a young lady who was known to be on the premises, he said he could probably take me to the right place, and that he certainly did.

"I must find some satisfaction in thinking that I should almost certainly have been in time, even if Mr. Thurlow had not been there, though I might not have been able to intervene so effectually, and what assistance I might have received from Wilkes can be a matter of conjecture only."

"You say you left Snacklit on the couch in the lounge?"

"Yes."

"He showed no sign of following you?"

"No. Nor did he look equal to doing it. I should have said that he was incapable of great exertion. . . . He might, of course, have got into a car."

"We know he didn't do that."

"Am I to conclude that it was for his murder that you have arrested Wilkes?"

"Not at all. We have no reason to suppose that he has been murdered. But the man who drove Miss Thurlow certainly was. She saw his body being wheeled to the incinerator, and when we drew the fire there were obvious human remains, which a few further hours would have reduced to unrecognizable ashes. No doubt it was done on Snacklit's orders, and that's probably why he disappeared in the way he did."

"Do I understand," the Professor asked, "that the heat of the incinerator would be sufficient to destroy a human body - even the bones - beyond recognition within so short a time?"

"Yes. That is so. The wonder really was that we were able to secure such definite evidence after the time which had elapsed. But you can understand why Wilkes was busy stoking the fire."

Professor Blinkwell said that that was certainly what he would be likely to do. He observed silently (it was not a matter to be spoken aloud) that Wilkes and Burfoot would probably be most justly hanged - as in fact they were - for the murder of the taxi-driver, on the unjust evidence of the remains of Mr. Snacklit which the furnace had been allowed insufficient time to consume entirely. Would Wilkes try to save himself by asserting the truth that it was Snacklit's body, and that Professor Blinkwell had pushed him in? It would be a most improbable thing, and, even if it were believed, it would be worse than useless to him, for he would have to admit that he had done nothing to intervene or denounce the crime. It would be to make his fate sure, even beyond the faint hope of reprieve which may follow conviction for the foulest crime, if a doubt of guilt, however slender, can be suggested to the Home Secretary's mind. . . .

Mr. Allenby rose. With a toneless forn;ality, he thanked Professor Blinkwell for the information he had given. Actually he saw no reason to doubt its substantial accuracy, apart only from the nature and extent of his knowledge of Snacklit, and his reasons for supposing that Irene would have been in his hands.

Professor Blinkwell rose also. He spoke with simple sincerity when he said that there was no occasion for thanks. Whatever little he had been able to do at Snacklit House had been a pleasure to him.
