On Saturday morning, Sherlock Holmes came with me to
Paddington Station.
‘This is a dangerous business, Watson, ’ he said. ‘Stay
near to Sir Henry. Do not let him walk on the moor alone
at night.’
‘Don't worry, Holmes,’ I said. ‘I have brought my army
revolver.’
‘Good,’ said Holmes. ‘Write to me every day. Tell me
what you see and hear. Tell me all the facts — everything.’
