Sir Mortimer

'And you, a man of science, believe that the creature is supernatural- something from another world?' asked Holmes ..
'I don't know what to believe,' said Dr Mortimer.
'But you must agree that the footprints were made by a living creature, not aghost?'
'When the hound first appeared two hundred and fifty years ago, it was real enough to tear out Sir Hugo's throat... but it was a supernatural hell-hound,' said Dr Mortimer.

Holmes believed that Sir Charles was in danger, but he did not believe in the hound.

I hope my friend Watson will go with you. If there is danger, you could not have a better man by your side.'
