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. From the cozy to the hardboiled, the literary to the pulp, and the classic to the contemporary, this book is the first book to explore the mystery genre’s many surprising horticultural connections. Meet plant-obsessed detectives and spooky groundskeeper suspects, witness toxic teas served in foul play, and tour the gardens—both real and imagined—that have been the settings for fiction’s ghastliest misdeeds.
