Martin has to deal with PC Mark Mylow's sister Sandra, a naturopath who has returned to Portwenn selling her natural remedies. Martin's effort to have her consult before "prescribing" any of her concoctions falls on deaf ears. Martin also has to deal with a odd family where the father is a bit of a ruffian and his two adult sons are in fear of him. They obviously rely on their mother to calm the home situation, but Martin is concerned when he observes that she is kept locked in a room to which he is refused admission. Al Large and receptionist Pauline start dating and a chance remark on the colour of his eyes leads him to believe that Bert may not be his biological father. Aunt Joan helps Al deal with his doubts.

[Sandra Mylow has been handing out herbal remedies without even seeing her patients]
Dr. Martin Ellingham: These can contain high levels of mercury, which given to somebody already suffering from a degree of psychosis, the effects can be catastrophic.
Sandra Mylow: I didn't realise she was that ill.
Dr. Martin Ellingham: Hadn't it struck you when she visited your clinic?
Sandra Mylow: She seemed fine.
Dr. Martin Ellingham: She didn't seem anything. You've never met her. Doreen Flint left this area eight years ago.

Excellent Use Balancing Plots
17 January 2018 | by HitchcocSee all my reviews

There are three plot lines here. The first and foremost involves a young man who comes to see Martin. His brother is dangerously ill as is he When Martin goes out to the ramshackle house in the country, he prescribes treatment for salmonella. During this time, the father, who is an amateur taxidermist, confronts Martin, driving him away. There is something wrong. The second plot line is about an herbalist who moves in and begins to belittle Doc Martin as she prescribes her remedies (which causes problems because of conflicting effects). She is seriously as combative as the Doc, but she is pushy and nasty. The third plot line is Bert's son, who realizes that Bert may not be his biological father. These things are nicely coordinated. I have only one concluding line referring to the ending. "Hi! I'm Larry. This is my brother Daryl and this is my other brother Daryl. Some wonderful bits all the way through.
