Murder is in full bloom, but can Steph and her sidekick Mouse weed out the killer? It's an invitation Steph Williams can't refuse when she's handpicked to compete in a flower show at the prestigious National Trust property of Coleton Fishacre. With the country's top garden designers as rivals and a stunning historic estate for inspiration, it feels like a dream come true. But things quickly turn thorny when the youngest competitor falls mysteriously ill and Steph suspects foul play. Her fears are confirmed when a scream echoes through the gardens, leading her to the shocking sight of a dead body at the foot of a cliff. With her trusty dog Mouse by her side, Steph's determined not to let the culprit slip through the cracks. Uncovering the truth in a garden full of suspects is no easy task, but Steph must see the wood for the trees before the murderer prunes out the competition - for good!
