Thanks for that above. I have now found the rest of things I have been missing bar one.

Where do you pick up the book "Great Wizards of the Twentieth Century"? I have looked in Florish and Blotts and the book just isn't there, and I can't see it in the rest of the chapters.

^
Hm, maybe I didn't buy it after all. I've got a bad memory. ^^;

When you're in the library (I think you go in there two or three times), mouse over every inch of the shelves. Or if it's not there, try different books that are on tables, etc.

Chapter twelve!

thank you thank you :-)

Using lesserpanda's template... well... we have the same contents! >.>

I seem to be missing the Circe chocolate frog card. I'll have to go through the book 1 again to find it.
