I do not know who he is,Watson,'he told me,'but I believe I know what kind of man he is.He is far too intelligent,too extraordinary a killer for our good friend Lestrade and his policemen in dresses to catch.No,he shall be mine. He is the criminal that I have waited for.To destroy him will be the greatest success of my life.I dream of it,Watson!I must destroy him! I cannot fail!
He was shaking with excitement.I had never seen him like this before.
That afternoon he went to Scotland Yard. When he came home,he was very quiet.Next day he appeared dressed in old, dirty clothes.
I am going to Whitechapel,'he told me.'As you know,I have rooms in several parts of London.For the next three days I shall live among the poor people of Whitechapel. Nobody will know who I am.I shall talk to them and listen to everything that they tell me.'
