how he came to be on Dartmoor when I thought that he was in Baker
Street working out the case of blackmailing.  I was somewhat bitter,
I will admit, that he had not trusted me with knowledge of his
movements, especially when he told me that he had wanted me to think
that he was in London.  It was hardly enough that he begged my
forgiveness for playing a trick on me, even though he assured me that
I had been invaluable to him. He tried to explain that, had his
presence been known, our very formidable opponents would have been
warned. As it was, he had been able to get about freely and was able
to throw his weight in at the critical moment. Appreciating the danger
I was in, he said, he had come down to examine the matter himself.
Cartwright, the little chap at the Express office in London, had
supplied all his needs & an extra pair of eyes.
