Ghelve blinks at the hobgoblin. (Intimidate check, roll of 15 on d20, +2 Str, total 17, success) Shrinking away, he shakes his head, "I put the locks in at the orphanage some twenty odd years ago. It's not that I don't care, it's just far beyond my concern. Let's remember one thing, locks are for honest people; if someone wants to get in, they will." He nods, over his shoulder, in the direction of the back of his shop and arches his eyebrows. "I certainly can't help you, unless you want to buy some locks or keys." He repeats the nod and eyebrow raise.
Carrach, Sando, Lia: You're pretty sure that Ghelve's indicating that there's something or someone in the back of his shop. Someone or something that he doesn't want to hear him talking about the kidnappings. He clearly knows more than he's shared so far.
Vorik: The locksmith seems to have acquired some sort of motor tic. A rather violent one, at that. It's funny that you haven't noticed this before. Qoll looks at you and nods at Ghelve, shrugging. All in all, this visit seems to have been more bizarre than helpful.
OOC: Here are the results of the Sense Motive checks from the above. Also, as you can see, I'm using Str for Intimidate, as I think it makes far more sense for the situation.
