Looks like we got ourselves a real "whodunit" here, rookie. Unfortunately it looks like the locals aren't willing to talk and the clues you got off the gnolls and murlocs are damn near worthless. We're going to have to initiate plan... be on the lookout for Two-Shoed Lou.
Two-Shoed Lou is a coincidental informant of mine who, ironically, makes his home at the Furlbrow's old pumpkin farm. Head over to the farm and find out what Lou knows.
If he gives you any guff tell him that Horatio sent you.
Completion
Look, we ain't got room for no more...
Horatio sent you? Right then... um, how can I help you?
He's not here is he? Heh, he knows I wasn't hidin from him, right? Was just tryin' to lay low and all that, ya know?
Notes
Run northwest to the pumpkin farm and pick up the brand new flight path!
