Hi,                                                                  
        I have been wondering about this ever since I've read the 
fifth book. Maybe I'm missing something, but I can't get what.       
	                                                             
        In Book Five, Aunt Petunia says she knows of the Dementors 
and about the wizards' prison Azkaban because she had once heard 
James Potter talking about it with Lily. How is this possible if, 
according to Book Four, the dementors joined the Ministry's side 
after Voldemort's regime ceased, and that this happened after the 
death of James and Lily 
Potter?                                                              
                                                      Neha.
