But the outsize influence that gardens and gardening have had on the mystery genre has been underappreciated. Now, Marta McDowell, a writer and gardener with a near-encyclopedic knowledge of the genre, illuminates the many ways in which our greatest mystery writers, from Edgar Allen Poe to authors on today’s bestseller lists, have found inspiration in the sinister side of gardens.
