distinction about it. That change in the footprints, for example.
What do you make of that?"

"Mortimer said that the man had walked on tiptoe down that
portion of the alley."

"He only repeated what some fool had said at the inquest. Why
should a man walk on tiptoe down the alley?"

"What then?"

"He was running, Watson--running desperately, running for his life,
running until he burst his heart--and fell dead upon his face."

"Running from what?"

"There lies our problem. There are indications that the man was
crazed with fear before ever he began to run."

"How can you say that?"

"I am presuming that the cause of his fears came to him across
the moor. If that were so, and it seems most probable, only a
man who had lost his wits would have run from the house instead
of towards it. If the gipsy's evidence may be taken as true, he
ran with cries for help in the direction where help was least
likely to be. Then, again, whom was he waiting for that night,
and why was he waiting for him in the yew alley rather than in
his own house?"
