Yep, it's the dialogue file, buggy as hell(questions @2 and @3 should theoretically go to A4, and it goes to A6. And @19 should be in answers, not Alassa's lines, and so on. And lines 26 and 27 are missing). In a nutshell, I recommend you choosing the "Why should I help you?" reply, then "Don't ask me. He was a bit strange, really, but a great lover. In any case, are you interested?". I doubt the author would go and fix it, as it is a one-day mod, but here's as the story goes in the English file:
@13 = ~My name is Alassa. I suppose you could say I'm a thief, although that's an awfully harsh word. I take what I need to survive from the people in Athkatla...and a little more I suppose; after all, everyone needs their luxuries.~
@14 = ~In the past, one of my suiters was a very wealthy man. A member of the city council, or something. He gave me little gifts every now and again, and I did the same for him.~
@15 = ~That was, until he died rather suddenly. He couldn't leave me his money for fear of scandal...he was a married man, you see. But he was kind enough to leave some of it for me, stashed in the graveyard somewhere.~
@16 = ~I can't go and collect it alone, though. It's no place for a girl to be sneaking around alone.~
@17 = ~So I thought maybe you'd be willing to come and find it with me. Of course, I'd split it with you, so you'd get something out of it.~
