One day he gave me his cocaine-bottle. 'Take it,
doctor,' he said. 'I do not need it any more.'
I was very pleased indeed at this news, and only one
thing that happened at this time worried me. A
woman was killed in Whitechapel, and people
began to talk again about Jack the Ripper. I
carefully checked where Holmes had been on the
night of the murder, and found that he had spent the
evening with two famous foreign detectives. I even
spoke to them both secretly, and so I was sure that
Holmes had not been in Whitechapel that night.
