Arthur Conan Doyle 
The Memoirs of Sherlock Holmes 

'I am afraid, Watson, that I shall have to go, ’ said Holmes, as we sat down together to our breakfast one morning.
'Go! Where to?’
'To Dartmoor; to King’s Pyland.’
I was not surprised. Indeed, my only wonder was that he had not already been mixed up in this extraordinary case, which was the one topic of conversation through the length and breadth of England. For a whole day my companion had rambled about the room with his chin upon his chest and his brows knitted, charging and recharging his pipe with the strongest black tobacco, and absolutely deaf to any of my questions or remarks. Fresh editions of every paper had been sent up by our news agent, only to be glanced over and tossed down into a corner. Yet, silent as he was, I knew perfectly well what it was over which he was brooding. There was but one problem before the public which could challenge his powers of analysis, and that was the singular disappearance of the favorite for the Wessex Cup, and the tragic murder of its trainer. When, therefore, he suddenly announced his intention of setting out for the scene of the drama it was only what I had both expected and hoped for.
