But isn't that a big if?  Do we have any indication prior to this that a 
spell ends if a person dies?  I mean, there is the obvious Lily is dead 
but her protection still holds (a third party was possibly involved).  
How about the portraits on the walls in Grimerwauld Place?  The one of 
SB's mother still has something holding it to the wall and we are told 
serious is the last of his line (thus the person who cast the charm is 
likely no longer on this side of the veil).

I am trying ot think of other examples, but can not seem to come up with 
any.  Anyone else have any?
