Next morning, at a quarter to seven o'clock, one of the man-servants, on
entering the room, found Mr. Mowbray lying on the floor, shot through the
head, and quite dead. Now we come to the curious circumstance of the
case. It was clear that after the bullet had passed out of the dead man's
head it had struck the tall clock in the room, right in the very centre
of the face, and actually welded together the three hands; for the clock
had a seconds hand that revolved round the same dial as the hour and
minute hands. But although the three hands had become welded together
exactly as they stood in relation to each other at the moment of impact,
yet they were free to revolve round the swivel in one piece, and had been
stupidly spun round several times by the servants before Mr. Wiley Slyman
was called upon the spot. But they would not move separately.

Now, inquiries by the police in the neighbourhood led to the arrest in
London of a stranger who was identified by several persons as having been
seen in the district the day before the murder, but it was ascertained
beyond doubt at what time on the fateful morning he went away by train.
If the crime took place after his departure, his innocence was
established. For this and other reasons it was of the first importance to
fix the exact time of the pistol shot, the sound of which nobody in the
house had heard. The clock face in the illustration shows exactly how the
hands were found. Mr. Slyman was asked to give the police the benefit of
his sagacity and experience, and directly he was shown the clock he
smiled and said:

"The matter is supremely simple. You will notice that the three hands
appear to be at equal distances from one another. The hour hand, for
example, is exactly twenty minutes removed from the minute hand--that is,
the third of the circumference of the dial. You attach a lot of
importance to the fact that the servants have been revolving the welded
hands, but their act is of no consequence whatever; for although they
were welded instantaneously, as they are free on the swivel, they would
swing round of themselves into equilibrium. Give me a few moments, and I
can tell you beyond any doubt the exact time that the pistol was fired."

Mr. Wiley Slyman took from his pocket a notebook, and began to figure it
out. In a few minutes he handed the police inspector a slip of paper, on
which he had written the precise moment of the crime. The stranger was
