A timely inheritance has enabled spunky, self-sufficient Tess Darcy to transform her late Aunt Iris' estate into a charming bed-and-breakfast inn. Aptly enough, among her first guests is a gaggle of gardening enthusiasts gathered together for the regional Iris Growers Convention—a thorny bunch more interested in digging up dirt than in weeding and watering. And when one of them turns up dead in Tess' magnificent garden—a cake knife planted firmly in her chest—it falls to the harried hostess to unearth the killer...before any more corpses spring up.
