Woodford, and, since nobody saw him at that house, it is at present
uncertain whether he went there before or after calling on Mr. Hurst. If
he went there first, then twenty minutes past five on the evening of the
twenty-third is the latest moment at which he is known to have been
alive; but if he went there after, there would have to be added to this
time the shortest possible time in which he could travel from the one
house to the other.

"But the question as to which house he visited first hinges on the
scarab. If he was wearing the scarab when he arrived at Mr. Hurst's
house, it would be certain that he went there first; but if it was not
then on his watch-chain, a probability would be established that he
went first to Woodford. Thus, you see, a question which may conceivably
become of the most vital moment in determining the succession of
property turns on the observation or non-observation by this housemaid
of an apparently trivial and insignificant fact."

"Has the servant made any statement on the subject, sir?" I ventured to
inquire.

"Apparently not," replied Dr. Thorndyke; "at any rate, there is no
reference to any such statement in the newspaper report, though,
otherwise, the case is reported in great detail; indeed, the wealth of

worth noting as being in itself a fact of considerable interest."

"In what respect, sir, is it of interest?" one of the students asked.

"Ah!" replied Dr. Thorndyke, "I think I must leave you to consider that
question yourself. This is an untried case, and we mustn't make free
