I'm very confused about this.  Draco wanted his father to buy him the 
hand of glory, but Lucius categorically refused.  Now, all of a sudden, 
not only does Draco possess this article but everyone (well, Ron 
anyway) seems to know he possesses it.  I have a vague memory of JKR 
saying in an interview something about Draco's hand of glory, and being 
surprised at the time, since I'm sure it isnt mentioned in any of the 
previous books that he had actually acquired it.  Is this a slip on 
Jo's part, or is it just my bad memory?
