Details: Laura is deeply shocked to hear on the news that Rosemary Boxer has been shot dead while looking into a problem with dying plants at Engleton Park. Surprised that Rosemary would take on such a job without her, Laura goes to tell Rosemary's mother, Barbara, what has happened - only to find Rosemary herself is with her mother. The three women go to see the body of the late Rosemary Boxer, only to find that the dead woman is in fact an archaeologist called Gemma Jackson, someone Rosemary knew in her college days. Rosemary and Laura use the real problem of the dying plants at Engleton Park as a foot in the door - and they soon find some dirty work at the cross-roads.
