TV series - "Adventures of Long John Silver" Ep 1 "The Necklace"

Silver is accused of murder! It's quite a violent introduction - a woman is killed and then her husband dies after giving a half description which pins it on Silver. So he's thrown in prison and Purity has to save him which is lovely. Actually based on that I wish the script was better - it was written by Martin Rackin and Kay Keavney.  Walter Brown is the pirate whodunnit and he's actually quite scary. Grant Taylor is a regular - I wonder if in part they cast Kit as Jim because his dad would be on set to keep an eye on him.
