d, naturally or otherwise, and his body have been
concealed; or he must have left the house unobserved. Let us take the
first case. This affair happened nearly two years ago. Now, he couldn't
have remained alive in the house for two years. He would have been
noticed. The servants, for instance, when cleaning out the rooms, would
have observed him."

Here Thorndyke interposed with an indulgent smile at his junior: "My
learned friend is treating the inquiry with unbecoming levity. We accept
the conclusion that the man did not remain in the house alive."

"Very well. Then did he remain in it dead? Apparently not. The report
says that as soon as the man was missed, Hurst and the servants together
searched the house thoroughly. But there had been no time or opportunity
to dispose of the body, whence the only possible conclusion is that the
body was not there. Moreover, if we admit the possibility of his having
been murdered--for that is what concealment of the body would
imply--there is the question: 'Who could have murdered him?' Not the
servants, obviously, and as to Hurst--well, of course, we don't know what
his relations with the missing man may have been--at least, I don't."

"Neither do I," said Thorndyke. "I know nothing beyond what is in the
newspaper report and what Berkeley has told us."

"Then we know nothing. He may have had a motive for murdering the man or
he may not. The point is that he doesn't seem to have had the
opportunity. Even if we suppose that he managed to conceal the body
temporarily, still there was the final disposal of it. He couldn't have
buried it in the garden with the servants about; neither could he have
burned it. The only conceivable method by which he could have got rid of
it would have been that of cutting it up into fragments and burying the
dismembered parts in some secluded spots or dropping them into ponds or
rivers. But no remains of the kind have been found, as some of them
probably would have been by now, so that there is nothing to support this
suggestion; indeed, the idea of murder, in this house at least, seems to
be excluded by the search that was made the instant the man was missed.

"Then to take the third alternative: Did he leave the house unobserved?
Well, it is not impossible, but it would be a queer thing to do. He may
have been an impulsive or eccentric man. We can't say. We know nothing
about him. But two years have elapsed and he has never t
