'Holmes!' I said in surprise. 'What are you doing here?'
'I am watching,' said Holmes. 'I am waiting for the murderer to show himself.'
'The murderer? Do you mean Selden? Selden is dead.'
'I know. I was on the tor last night and saw what happened,' Holmes said. 'Someone wanted to kill Sir Henry Baskerville, not Selden.'
'But how long have you been here?' I asked. 'And why are you here in secret?'
'I came here on the same day as you,' answered Sherlock Holmes. 'I came in secret because the murderer is clever. He will not show himself if he knows I am here.'
