"It's about the Furlbrows," you say. "Nice folks," Lou says. "Heard they moved off to Stormwind City. Maybe you should check in on them there." "They just died," you explain. "Laine wanted to know anything you knew about this." Lou pales. "Right, then...um, how can I help you?" he says, laughing nervously. "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? Listen, I really shouldn't be talkin' to you, but I owe Horatio a favor or two, so I might be able to point you in the right direction." Abruptly, he picks up a nearby object that looks like a rock, but is big enough to conceal you, then hands it to you. "Take this to the back of the Jangolode Mine, southwest of here, then hide in it."
Accept. Head off to the Jangolode Mine. Decline. This could be a trap. Besides, you might be better off taking a look around here instead.
