I saw the interview, and part of me agrees that she shouldn't be tarred with the same brush as her husband, but another part knows that if Mr Dog had four expensive coffee machines I would 100% know about it. Similarly a Jaguar.
I know they lived pretty much separate lives, but the house isn't so big that things like that wouldn't be obvious, surely?
If she's right about the necklace she says he gave her, I feel sorry for her about that though - it must be a blow to find out that a present of that nature wasn't given with kindness.
