In Dr Jekyll and Mr Hyde, Hyde, upon meeting Utterson for the first time, immediately gives him his address. Why?
​
Utterson is not supposed to know that he's really Jekyll. So why give your address to a man you've just met who had been waiting for you in the shadows? Hyde obviously knows who Utterson is, but Utterson can't know that and telling him where he lives risks being discovered. There is no benefit to it. And Utterson doesn't even find that part strange: That a complete stranger of questionable character would tell him where he lived.
What gives?
