Holmes and I were surprised. This was a very strange story. I did not believe that Sir Charles Baskerville had been killed Bas by a gigantic black dog. But I wanted to know the truth. "Who else saw these footprints?" asked Sherlock Holmes. His bright eyes shone and he leant forward in his chair. No one else the footprints,' answered Dr Mortimer There was a lot of rain in the night. By morning, the footprints had been washed away.' How large were the footprints? Were they larger than the footprints of a sheepdog?' Yes, Mr Holmes, much larger. They were not the prints brin an ordinary dog.' Also, you say that Sir Charles ran away from this dog mus How do you know? asked Holmes.
