Legend

After dispatching the last thief you go over to Wallace who is failing at trying to stay alive.

"Argh, damn it. If you'd gotten here a lot sooner, this wouldn't have happened! (gurgle)"
"Well don't you have notes and documents with the information about the Guild?"
"(Cough) Of course! I couldn't remember it all! I got it right here."
"Good, then I'll just take this then and get the credit!" you say and finish off Wallace.

You quickly search Wallace's body and gather his parchment book of his findings, maps, and notes. You don't have too much time though since more thieves come running down the sewers and see you. You run and manage to hide, but you find that the thieves seem to be out in force. They're determined to track you down and probably have all the vital exits to the top blocked.
