"It was too far for me to go, weak and ill as I was. I determined
to wait until I got back to town before telling my story to the
police. It was a little past six when I arrived, so I went first
to have my wound dressed, and then the doctor was kind enough to
bring me along here. I put the case into your hands and shall do
exactly what you advise."

We both sat in silence for some little time after listening to
this extraordinary narrative. Then Sherlock Holmes pulled down
from the shelf one of the ponderous commonplace books in which he
placed his cuttings.

"Here is an advertisement which will interest you," said he. "It
appeared in all the papers about a year ago. Listen to this:
'Lost, on the 9th inst., Mr. Jeremiah Hayling, aged
twenty-six, a hydraulic engineer. Left his lodgings at ten
o'clock at night, and has not been heard of since. Was
dressed in,' etc., etc. Ha! That represents the last time that
the colonel needed to have his machine overhauled, I fancy."

"Good heavens!" cried my patient. "Then that explains what the
girl said."

"Undoubtedly. It is quite clear that the colonel was a cool and
desperate man, who was absolutely determined that nothing should
stand in the way of his little game, like those out-and-out
pirates who will leave no survivor from a captured ship. Well,
every moment now is precious, so if you feel equal to it we shall
go down to Scotland Yard at once as a preliminary to starting for
Eyford."
