The Hound of the Baskervilles: The Problem

I confess at these words a shudder passed through me. There was a
thrill in the doctor’s voice which showed that he was himself
deeply moved by that which he told us. Holmes leaned forward in
his excitement and his eyes had the hard, dry glitter which shot
from them when he was keenly interested.

“You saw this?”

“As clearly as I see you.”

“And you said nothing?”

“What was the use?”

“How was it that no one else saw it?”

“The marks were some twenty yards from the body and no one gave
them a thought. I don’t suppose I should have done so had I not
known this legend.”

“There are many sheep-dogs on the moor?”

“No doubt, but this was no sheep-dog.”

“You say it was large?”

“Enormous.”

“But it had not approached the body?”

“No.”

“What sort of night was it?”

“Damp and raw.”

“But not actually raining?”

“No.”

“What is the alley like?”

“There are two lines of old yew hedge, twelve feet high and
impenetrable. The walk in the centre is about eight feet across.”

“Is there anything between the hedges and the walk?”

“Yes, there is a strip of grass about six feet broad on either
side.”

“I understand that the yew hedge is penetrated at one point by a
gate?”

“Yes, the wicket-gate which leads on to the moor.”

“Is there any other opening?”

“None.”

“So that to reach the yew alley one either has to come down it
from the house or else to enter it by the moor-gate?”

“There is an exit through a summer-house at the far end.”

“Had Sir Charles reached this?”

“No; he lay about fifty yards from it.”

“Now, tell me, Dr. Mortimer—and this is important—the marks which
you saw were on the path and not on the grass?”

“No marks could show on the grass.”

“Were they on the same side of the path as the moor-gate?”

“Yes; they were on the edge of the path on the same side as the
moor-gate.”

“You interest me exceedingly. Another point. Was the wicket-gate
closed?”

“Closed and padlocked.”

“How high was it?”

“About four feet high.”

“Then anyone could have got over it?”

“Yes.”

“And what marks did you see by the wicket-gate?”

“None in particular.”

“Good heaven! Did no one examine?”

“Yes, I examined, myself.”

“And found nothing?”

“It was all very confused. Sir Charles had evidently stood there
for five or ten minutes.”

“How do you know that?”

“Because the ash had twice dropped from his cigar.”

“Excellent! This is a colleague, Watson, after our own heart. But
the marks?”

“He had left his own marks all over that small patch of gravel. I
could discern no others.”

Sherlock Holmes struck his hand against his knee with an
impatient gesture.

“If I had only been there!” he cried. “It is evidently a case of
extraordinary interest, and one which presented immense
opportunities to the scientific expert. That gravel page upon
which I might have read so much has been long ere this smudged by
the rain and defaced by the clogs of curious peasants. Oh, Dr.
Mortimer, Dr. Mortimer, to think that you should not have called
me in! You have indeed much to answer for.”
