The Poisoned Peony. A Purrlock Holmes Mystery, #1

When Maisie Hartwell inherits her aunt's North Yorkshire cottage, she expects bookshelves, garden beds, and the quiet work of grief. She does not expect Purrlock Holmes. Silver-grey, amber-eyed, and possessed of opinions about everything, Purrlock has been waiting in the cottage since Cecily died - because Cecily's death was not the peaceful ending the village of Thornwick-on-Wren has decided it was.
There is a murderer who has been very careful. There are things only Maisie can find. And there are things only Purrlock knows. A retired librarian with a gift she has spent forty years explaining away, Maisie is done explaining things away. Some secrets are buried in the garden. Some are kept by the cat. The Poisoned Peony is the first book in the Purrlock Holmes Mystery series - a paranormal cozy mystery set in the English countryside, where the gardens are extraordinary, the tea is always on, and a silver-grey cat on the kitchen table is never, ever simply a cat.
