Sir Henry Baskerville and Dr Mortimer were ready upon the appointed day, and we started as arranged for Devonshire. Mr Sherlock Holmes drove with me to the station and gave me his last parting injunctions and advice.

"What sort of facts?" I asked. "Would it not be well in the first place to get rid of this Barrymore couple?" "I will do my best." "You have arms, I suppose?" "Who is he, then?"
