After you have completed the whois ...solved the Whitechapel murders! you can then go back to Dr Bond, he will immediately run off to try and catch his ride out of town, but he forgets to give you the notes he promised.
Go to 'Approaching the Wharf Near Nightengale Ln.' and catch up to him, he will attempt to give you some notes as he gets in his carriage but they blow away.
Now go into 'A FOG OVER THE WHARF!' and wait, you get a lot of dramatic details and statements about Jack the Ripper, who then appears and murders you.
You get the whois ....took the true identity of Jack, the Ripper to their grave!
