"Now, the personator was clearly not Hurst himself, for he would have been recognized by his housemaid; he was therefore either Godfrey Bellingham or Mr. Jellicoe or some other person; and as no other person was mentioned in the newspaper reports I confined my speculations to these two.

"And, first, as to Godfrey Bellingham. It did not appear whether he was or was not known to the housemaid, so I assumed—wrongly, as it turns out—that he was not. Then he might have been the personator. But why should he have personated his brother? He could not have already committed the murder. There had not been time enough. He would have had to leave Woodford before John Bellingham had set out for Charing Cross. And even if he had committed the murder, he would have no object in raising this commotion. His cue would have been to remain quiet and know nothing. The probabilities were all against the personator being Godfrey Bellingham.

"Then could it be Mr. Jellicoe? The answer to this question is contained in the answer to the further question: 'What could have been the object of the personation?'

"What motive could this unknown person have had in appearing, announcing himself as John Bellingham, and forthwith vanishing? There could only have been one motive: that, namely, of fixing the date of John Bellingham's disappearance—of furnishing a definite moment at which he was last seen alive.

"But who was likely to have had such a motive? Let us see.

"I said just now that if Mr. Jellicoe had murdered John Bellingham and disposed of the body in the mummy-case, he would have been absolutely safe for the time being. But there would be a weak spot in his armor. For a month or more the disappearance of his client would occasion no remark. But presently, when he failed to return, inquiries would be set on foot; and then it would appear that no one had seen him since he left Queen Square. Then it would be noted that the last person with whom he was seen was Mr. Jellicoe. It might, further, be remembered that the mummy had been delivered to the Museum some time after the missing man was last seen alive. And so suspicion might arise and be followed by disastrous investigations. But supposing it should be made to appear that John Bellingham had been seen alive more than a month after his interview with Mr. Jellicoe and some weeks after the mummy had been deposited in the Museum? Then Mr. Jellicoe would cease to be in any way connected with the disappearance and henceforth would be absolutely safe.

"Hence, after carefully considering this part of the newspaper report, I came to the conclusion that the mysterious occurrence at Mr. Hurst's house had only one reasonable explanation, namely, that the visitor was not John Bellingham, but some one personating him; and that that some one was Mr. Jellicoe.

"It remains to consider the case of Godfrey Bellingham and his daughter, though I cannot understand how any sane person can have seriously suspected either" (here Inspector Badger smiled a sour smile). "The evidence against them was negligible, for there was nothing to connect them with the affair save the finding of the scarab on their premises; and that event which might have been highly suspicious under other circumstances, was robbed of any significance by the fact that the scarab was found on a spot which had been passed a few minutes previously by the other suspected party, Hurst. The finding of the scarab did, however, establish two important conclusions: namely, that John Bellingham had probably met with foul play, and that of the four persons present when it was found, one at least had had possession of the body. As to which of the four was the one, the circumstances furnished only a hint, which was this: If the scarab had been purposely dropped, the most likely person to find it was the one who dropped it. And the person who discovered it was Mr. Jellicoe.

"Following up this hint, if we ask ourselves what motive Mr. Jellicoe could have had for dropping it—assuming him to be the murderer—the answer is obvious. It would not be his policy to fix the crime on any particular person, but rather to set up a complication of conflicting evidence which would occupy the attention of investigators and divert it from himself.

"Of course, if Hurst had been the murderer, he would have had a sufficient motive for dropping the scarab, so that the case against Mr. Jellicoe was not conclusive; but the fact that it was he who found it was highly significant.
