have evident knowledge of Azkaban? Harry was actively involved in 
the WW for a couple of years without knowing of Azkaban.

I don't think DD would lie about something like this.  What I think 
happened is Petunia knows a lot more that she has ever admitted to, 
but she is usually so controlled that she keeps it hidden.  When 
Dudley is attacked she is so shaken that she forgot to control what 
she was saying.  I'm not sure that she has kept in touch with DD.  
It's more likely that his howler reminded her about the blood 
protection and the agreement she made when she agreed to raise Harry.
