supposed to be in London. My
hardships were not so great as you imagined, though such trifling
details must never interfere with the investigation of a case. I
stayed for the most part at Coombe Tracey, and only used the hut
upon the moor when it was necessary to be near the scene of
action. Cartwright had come down with me, and in his disguise as
a country boy he was of great assistance to me. I was dependent
upon him for food and clean linen. When I was watching Stapleton,
Cartwright was frequently watching you, so that I was able to
keep my hand upon all the strings.

"I have already told you that your reports reached me rapidly,
being forwarded instantly from Baker Street to Coombe Tracey.
They were of great service to me, and especially that one
incidentally truthful piece of biography of Stapleton's. I was
able to establish the identity of the man and the woman and knew
at last exactly how I stood. The case had been considerably
complicated through the incident of the escaped convict and the
relations between him and the Barrymores. This also you cleared
up in a very effective way, though I had already come to the same
conclusions from my own observations.

"By the time that you discovered me upon the moor I had a

do so we had to use Sir Henry, alone and apparently unprotected,
as a bait. We did so, and at the cost of a severe shock to our
client we succeeded in completing our case and driving Stapleton
to his destruction. That Sir Henry should have been exposed to
this is, I must confess, a reproach to my management of the case,
but we had no means of foreseeing the terrible and paralyzing
spectacle which the beast presented, nor could we predict the fog
which enabled him to burst upon us at such short notice. We
succeeded in our object at a cost which both the specialist and
Dr. Mortimer assure me will be a temporary one. A long journey
may enable our friend to recover not only from his shattered
nerves but also from his wounded feelings. His love for the lady
was deep and sincere, and to him the saddest part of all this
black business was that he should have been deceived by her.
