Interesting insight and development—I like the way you portrayed Alison's trains of thought here, her wondering so much about the Professor's intentions, wondering what she wanted herself, thinking of Peter and how terribly ironical his fate had been, and finally finding that she needed closure so much, she needed to know what had really happened to Peter never mind the risk for herself. The Master's reactions to her request were quite interesting, I'm very curious to see how it all unfolds in the last chapter :) Looks like a good conclusion in the making!

Typos I spotted:
"If he wanted her money he would be able to make her give them to him anyway.": give it
"evade having her sister to go with her.": having her sister go with her?
"she rather have it out before she lost her nerve completely.": she'd rather?
"But even if Allison could believe him": Alison
