A fabulous author, I tell you.
I'm thoroughly enjoying the lastest in her Cottage Tales of Beatrix Potter series. These splendid, fanciful mysteries have a wide cast of characters, including Beatrix Potter, William Heelis, Tabitha Twitchet (Senior Village Cat), Rascal the terrier, and Bosworth Badger XVII, who records the History of the Land Between the Lakes. The dialogue is a fabulously woven tapestry of human and animal conversations and the tone of the narration makes you feel like you're there.
Start at the beginning-- The Tale of Hill Top Farm.

I also VERY VERY highly recommend the Victorian/Edwardian mysteries she has written with her husband, under the name Robin Paige. Death at Bishop's Keep is the first. There are 12 currently, and while they have no plans at the moment to write more (sadly), the door has been left open. I, for one, am hoping the write a few more. But if not, I suppose I'll just keep rereading them!
