This was such a good episode. Belinda Lang plays a woman named Quinnie that has a TV series on plants and landscaping. Rosemary gets hurt when a scaffold she is on collapses and she ends up in the hospital. Laura her other half that fixes gardens etc is left by herself. Later it looks like the scaffold accident was to hurt someone else. Lots of enemies and lots of mystery on the set filming the landscape program. A woman dies in a pool which is also suspicious. It seems the "accidents" have to do with a man that scammed people out of money from the past and some people where catching up on they crooks.
Felicity Kendal/Rosemary is a great actress too. At times very funny when scared. In "They Understand Me in Paris" she was very funny trying to speak French and looked really silly trying to get people to understand her. She played in in Artsnight 2016.
Pam Ferris/Laura who is Rosemary's helper acts now in "Call the Midwife" which is on public TV that in many episodes up to 2016.
Belinda Lang played parts in a number of series most of them I liked. Alleyn Mystery, Citizen Khan which is very funny, Midsomer Murder and more. She is also married to Hugh Fraser who played "Hastings" in the Agatha Christie - Poirot series which I also love. Rosemary & Thyme go back to 2003 so the info I have is up to 2003. Great series Rosemary & Thyme.
