I used this recently for my Black Company Game, which had a group of 6, all level 2. I changed out the werewolves for the wereleopards in the Black Company setting (which were all between level 4 and 5).
One of the fighters and the thief/ranger was immediately suspicious of the Mother, however they didn't question her too much, and left her to talk to the Academician.
The party and I came to the conclusion that the module was fun, needed a bit more substance to it (although they do tell you that it's a micro adventure that lasts about 30 minutes), and a little railroady.
Besides that, the party had fun with it anyways.
