I think I know what one of the horcruxes is.

Exodusts:
That is a decent point. However, I think DD is wrong about Nagini 
being a Horcrux for the reason that he is wrong about the details of 
Frank's death. DD tells Harry that LV "used Nagini to kill" the old 
man. We know this is flat wrong, from the opening of GoF, LV did it 
himself. If DD is wrong about that, he could be wrong about Nagini 
full stop. Unless that was a mistake by JKR (pretty embarassing if it 
was). Maybe LV killed Frank himself because he was angry or annoyed 
with Frank's backtalk, but left Pettigrew to kill Cedric because it 
was just an administrative job (to get rid of the spare).

Exodusts:
The quote reads: "The wealthy man who owned the Riddle House these 
days neither lived there nor put it to any use; they said in the 
village that he kept it for 'tax reasons', though nobody was very 
clear what these might be. The wealthy owner continued to pay Frank 
to do the gardening, however."

In the light of what we have learnt since GoF, that throwaway passage 
does look more suspicious. Maybe LV bought the house, through an 
agent, at the most recent of its sales? Especially given his 
propensity to collect stuff important to him, and the fact that it 
would be meaningful for him to own the great house that once lorded 
it over the neighbourhood where his mother grew up in squalor. 
Ravenclaw Horcrux hidden in the Riddle House, perhaps - although that 
would be mighty close to the Ring that was hidden at the Gaunts? And 
wouldn't DD have searched it already?
