At +4 INT and +4 WIS, Abrogail Thrune would probably figure it out, given a minute, if she were just given one minute to think.

She's not told in advance what she's to be questioned about?  So somebody can see her reactions, so she doesn't have time to invent a story, according to negotiated conditions?  But even at this little Splendour she can control herself.  Does that imply that it's just her testimony to be transmitted and not her thoughts?  How would that end up relevant to a bid by Keltham to have her returned to him?

"Required under what authority?" she says, making her voice and expression empty, for at this Splendour she will not essay an active deception.  "Few compacts with Keltham were signed by me or in my name; and my compact with Asmodeus does not require me to obey all Hell's orders so long as I serve Him well through Cheliax."  Will it violate an oath if she lies?
