to this, I would draw your attention to the fact that,
if Alec Cunningham's narrative was correct, and if the assailant, after
shooting William Kirwan, had instantly fled, then it obviously could not
be he who tore the paper from the dead man's hand. But if it was not he,
it must have been Alec Cunningham himself, for by the time that the old
man had descended several servants were upon the scene. The point is a
simple one, but the Inspector had overlooked it because he had started
with the supposition that these county magnates had had nothing to do
with the matter. Now, I make a point of never having any prejudices,
and of following docilely wherever fact may lead me, and so, in the
very first stage of the investigation, I found myself looking a little
askance at the part which had been played by Mr. Alec Cunningham.

"And now I made a very careful examination of the corner of paper which
the Inspector had submitted to us. It was at once clear to me that it
formed part of a very remarkable document. Here it is. Do you not now
observe something very suggestive about it?"

"It has a very irregular look," said the Colonel.

"My dear sir," cried Holmes, "there cannot be the least doubt in the
world that it has been written by two persons doing alternate words.
When I draw your attention to the strong t's of 'at' and 'to', and ask
you to compare them with the weak ones of 'quarter' and 'twelve,' you
will instantly recognize the fact. A very brief analysis of these
four words would enable you to say with the utmost confidence that the
'learn' and the 'maybe' are written in the stronger hand, and the 'what'
in the weaker."

"By Jove, it's as clear as day!" cried the Colonel. "Why on earth should
two men write a letter in such a fashion?"

"Obviously the business was a bad one, and one of the men who distrusted
the other was determined that, whatever was done, each should have an
equal hand in it. Now, of the two men, it is clear that the one who
wrote the 'at' and 'to' was the ringleader."

"How do you get at that?"

"We might deduce it from the mere character of the one hand as compared
with the other. But we have more assured reasons than that for supposing
it. If you examine this scrap with attention you will come to the
conclusion that the man with the stronger hand wrote all his words
first, leaving blanks for the other to fill up. These blanks were not
always sufficient, and you can see that the second man had a
