Pippin:
I thought Neri was asking for the canon that the diary could have
made present day Voldemort stronger. But no problem.
The evidence that someone besides Lucius is involved 
is strong enough, IMO.  In the first place, Dobby refers to a plot. 
He must have heard Lucius discuss it with someone. Who?

According to Dumbledore, Lucius did not know that the Diary would do
anything but open the Chamber. If that's so, then the Malfoys didn't know it
would make present day Voldemort stronger, and that's consistent with 
Lucius and Narcissa not trying to find their old master. But if the fact 
that the diary would make present day Voldemort stronger is relevant, 
then *somebody* must have known that.
