Walsh took the notes that Sayers left for a Wimsey/Vane mystery, and finished it. I'd rather they had simply published the notes. It is quite obvious where Sayers notes ended, and Walsh is simply incapable of writing in anything like Sayers' voice. And she hasn't a clue about the psychology of the Lord and Lady Peter. Walsh may well write decent novels of her own, but I wish she'd kept her hands off Peter and Harriet.
