"You'll be telling us next you know who did it," Roger smiled.
Mr. Chitterwick smiled back. "Oh, I know that."
"What!" exclaimed five voices in chorus.
"I know that, of course," said Mr. Chitterwick modestly. "You've practically told me that yourselves. Coming last of all, you see, my task was comparatively simple. All I had to do was to sort out the true from the false in everybody else's statements, and - well, there was the truth."
The rest of the Circle looked their surprise at having told Mr. Chitterwick the truth without knowing it themselves.
Mr. Chitterwick's face took on a meditative aspect. "Perhaps I may confess now that when our President first propounded his idea to us, I was filled with dismay. I had had no practical experience of detecting, I was quite at a loss as to how to set about it, and I had no theory of the case at all. I could not even see a starting - point. The week flew by, so far as I was concerned, and left me exactly where I had been at its beginning. On the evening Sir Charles spoke he convinced me completely. The next evening, for a short time, Mrs. Fielder - Flemming convinced me too.
"Mr. Bradley did not altogether convince me that he had committed the murder himself, but if he had named any one else then I should have been convinced; as it was, he convinced me that his - his discarded mistress theory," said Mr. Chitterwick bravely, "must be the correct one. That indeed was the only idea I had had at all, that the crime might be the work of one of Sir Eustace's - h'm! - discarded mistresses.
"But the next evening Mr. Sheringham convinced me just as definitely that Mr. Bendix was the murderer. It was only last night, during Miss Dammers's exposition, that I at last began to realise the truth."
"Then I was the only one who didn't convince you, Mr. Chitterwick?" Miss Dammers smiled.
"I'm afraid," apologised Mr. Chitterwick, "that is so."
He mused for a moment. "It is really remarkable, quite remarkable, how near in some way or other everybody got to the truth of this affair. Not a single person failed to bring out at least one important fact, or make at least one important deduction correctly. Fortunately, when I realised that the solutions were going to differ so widely, I made copious notes of the preceding ones and kept them up to date each evening as soon as I got home. I thus had a complete record of the productions of all these brains, so much superior to my own."
"No, no," murmured Mr. Bradley.
"Last night I sat up very late, poring over these notes, separating the true from the false. It might perhaps interest members to hear my conclusions in this respect?" Mr. Chitterwick put forward the suggestion with the utmost diffidence.
Everybody assured Mr. Chitterwick that they would be only too gratified to hear where they had stumbled inadvertently on the truth.
CHAPTER XVIII
MR. CHITTERWICK consulted a page of his notes. For a moment he looked a little distressed. "Sir Charles," he began. "Er - Sir Charles . . ." It was plain that Mr. Chitterwick was finding difficulty in discovering any point at all on which Sir Charles had been right, and he was a kindly man. He brightened. "Oh, yes, of course. Sir Charles was the first to point out the important fact that there had been an erasure on the piece of notepaper used for the forged letter. That was - er - very helpful.
"Then he was right too when he put forward the suggestion that Sir Eustace's impending divorce was really the mainspring of the whole tragedy. Though I am afraid," Mr. Chitterwick felt compelled to add, "that the inference he drew was not the correct one. He was quite right in feeling that the criminal, in such a clever plot, would take steps to arrange an alibi, and that there was, in fact, an alibi in the case that would have to be circumvented. But then again it was not Lady Pennefather's.
"Mrs. Fielder - Flemming," continued Mr. Chitterwick, "was quite right to insist that the murder was the work of somebody with a knowledge of criminology. That was a very clever inference, and I am glad," beamed Mr. Chitterwick, "to be able to assure her that it was perfectly correct. She contributed another important piece of information too, just as vital to the real story underlying this tragedy as to her own case, namely that Sir Eustace was not in love with Miss Wildman at all but was hoping to marry her simply for her money. Had that not been the case," said Mr. Chitterwick, shaking his head, "I fear, I very much fear, that it would have been Miss Wildman who met her death instead of Mrs. Bendix."
"Good God!" muttered Sir Charles; and it is perhaps as great a tribute as Mr. Chitterwick was ever to receive that the K.C. accepted this startling news without question.
"That clinches it," muttered Mr. Bradley to Mrs. Fielder - Flemming. "Discarded mistress."
Mr. Chitterwick turned to him. "As for you, Bradley, it's astonishing how near you came to the truth. Amazing!" Mr. Chitterwick registered amazement. "Even in your first case, against yourself, so many of your conclusions were perfectly right. The final result of your deductions from the nitrobenzene, for instance; the fact that the criminal must be neat - fingered and of a methodical and creative mind; even, what appeared to me at the time just a trifle far - fetched, that a copy of Taylor would be found on the criminal's shelves.
"Then beyond the fact that No. 4 must be qualified to 'must have had an opportunity of secretly obtaining a sheet of Mason's notepaper,' all twelve of your conditions were quite right, with the exception of 6, which does not admit of an alibi, and 7 and 8, about the Onyx pen and Harfield's ink. Mr. Sheringham was right in that matter with his rather more subtle point of the criminal's probable unobtrusive borrowing of the pen and ink. Which is exactly what happened, of course, with regard to the typewriter.
"As for your second case - well!" Mr. Chitterwick seemed to be without words to express his admiration of Mr. Bradley's second case. "You reached to the truth in almost every particular. You saw that it was a woman's crime, you deduced the outraged feminine feelings underlying the whole affair, you staked your whole case on the criminal's knowledge of criminology. It was really most penetrating."
"In fact," said Mr. Bradley, carefully concealing his gratification, "I did everything possible except find the murderess."
"Well, that is so, of course," deprecated Mr. Chitterwick, somehow conveying the impression that after all finding the murderess was a very minor matter compared with Mr. Bradley's powers of penetration.
"And then we come to Mr. Sheringham."
"Don't!" implored Roger. "Leave him out."
"Oh, but your reconstruction was very clever," Mr. Chitterwick assured him with great earnestness. "You put a new aspect on the whole affair, you know, by your suggestion that it was the right victim who was killed after all."
"Well, it seems that I erred in good company," Roger said tritely, with a glance at Miss Dammers. "But you didn't err," corrected Mr. Chitterwick. "Oh?" Roger showed his surprise. "Then it was all aimed against Mrs. Bendix?"
Mr. Chitterwick looked confused. "Haven't I told you about that? I'm afraid I'm doing this in a very muddle - headed way. Yes, it is partially true to say that the plot was aimed against Mrs. Bendix. But the real position, I think, is that it was aimed against Mrs. Bendix and Sir Eustace jointly. You came very near the truth, Mr. Sheringham, except that you substituted a jealous husband for a jealous rival. Very near indeed. And of course you were entirely right in your point that the method was not suggested by the chance possession of the notepaper or anything like that, but by previous cases."
"I'm glad I was entirely right over something," murmured Roger.
"And Miss Dammers," bowed Mr. Chitterwick, "was most helpful. Most helpful."
