t much. We know that there is someone who
has the facts if we can only find her. What do you think we should do?"

"Let Holmes know all about it at once. It will give him the clue for
which he has been seeking. I am much mistaken if it does not bring him
down."

I went at once to my room and drew up my report of the morning's
conversation for Holmes. It was evident to me that he had been very busy
of late, for the notes which I had from Baker Street were few and short,
with no comments upon the information which I had supplied and hardly
any reference to my mission. No doubt his blackmailing case is absorbing
all his faculties. And yet this new factor must surely arrest his
attention and renew his interest. I wish that he were here.

October 17th. All day today the rain poured down, rustling on the ivy
and dripping from the eaves. I thought of the convict out upon the
bleak, cold, shelterless moor. Poor devil! Whatever his crimes, he has
suffered something to atone for them. And then I thought of that other

fantastic hills. In the distant hollow on the left, half hidden by the
mist, the two thin towers of Baskerville Hall rose above the trees. They
were the only signs of human life which I could see, save only those
prehistoric huts which lay thickly upon the slopes of the hills. Nowhere
was there any trace of that lonely man whom I had seen on the same spot
two nights before.

As I walked back I was overtaken by Dr. Mortimer driving in his dog-cart
over a rough moorland track which led from the outlying farmhouse of
Foulmire. He has been very attentive to us, and hardly a day has passed
that he has not called at the Hall to see how we were getting on. He
insisted upon my climbing into his dog-cart, and he gave me a lift
