"For instance, if I should hypnotize a young man, and say that at eight
o'clock, when he hears the clock strike, he should at once go downstairs
and get a glass of water, he would undoubtedly do it when the clock
struck eight. But if the clock did not strike eight, supposing some one
had removed the striker, and when near the hour some one occupied his
attention so that he did not notice the time, in all probability he
would not obey orders. It requires some special occurrence which has
been described in connection with the act to suggest it again to his
mind.

"In my opinion, the best we can do is to let Murphy ride the race, and
to take all precautions possible to prevent any man waving his
handkerchief to Murphy during the race. Of course, to have any real
effect on the race, the person waving his handkerchief as a signal for
Murphy to 'pull' Emperor must do so far enough from the home stretch to
make it certain that Emperor can be prevented from winning without
attracting especial attention, which could not be done in case Emperor
was in the lead if the signal was given close to the Grand Stand. We,
therefore, must look out for our man, if such a man there be, some
distance down the race-track.

"Now, if you will go to the track with me to-morrow we will station
ourselves in places where we think it likely that such a person would
stand, and keep a sharp watch for a thin, dark man with a scar on his
cheek. Will you join me?"

I assured him I would be more than willing to do so, as I was very much
interested in the case.

"Good! Now, this is my plan. I shall take Mike Falan with me, and he is
worth half a dozen men in the case of a row. I have also engaged three
private detectives to be on the watch at the entrance to the Grand
Stand, and another at the entrance to the grounds, while a fifth is to
station himself at the side of the track, and do sentinel duty about the
half-mile post, with orders to report to me the moment Simms puts in an
appearance, and to have him shadowed. Of course, this elaborate plot may
exist only in my imagination, but if, as I believe, there is a carefully
arranged scheme to beat Blake's horse, we shall have done him a good
turn, and perhaps saved him a lot of money. I must go now, but don't
fail to meet me to-morrow at eleven, at the track. You will find me in
front of the Grand Stand."

The next morning when I arrived at the track I found Dr. Watson in
