Orpheus in the Undergrowth - S2-E2
Plot hole: When Jeremy stopped to drink his water, which turned out to be vodka and which killed him via a heart attack, why did he hide himself away, surrounded by plants and only found by his mobile ringing? And why would he put the lid back on the bottle in the throes of a heart attack?

Continuity mistake: When Laura decides to talk to Helena for the second time, she's wearing gardening gloves, but as she walks away, the gloves are gone.

Continuity mistake: On the second night at Julia's, Laura has insomnia again and this time she gets up and goes down to the gardens, which are bathed in light - much more than from a full moon. When Mr Elliott turns up while the girls are working, Laura says to him "Were you out star gazing last night, Mr Elliott?" And he says "Indeed I was, a partial lunar eclipse in wonderful darkness."

Other mistake: In the beginning, when Julia shows the girls the private gardens, Julia is standing behind them, until suddenly she is standing beside them as she says "Impressed?"

Continuity mistake: When Laura goes to see Helena, after they've made up, Helena has a chisel in her right hand, but not for long - suddenly, it's gone.

Continuity mistake: When Rosemary finds her second bunch of smooth ink cap mushrooms and picks one, then declares, "Fungus Ferguson. My old college professor," who will be able to tell Rosemary what is special about smooth ink caps - this has been bugging Rosemary for days - and then grabs her cardigan without dealing with the mushroom in her hands, which is no longer to be seen.

Other mistake: The girls are staying with Julia whose house starts on the first floor, so she has no direct access to the gardens, but when Laura comes back to Julia's place, she enters via the gardens.

Continuity mistake: In the beginning, the girls have one wheelbarrow out of the Land Rover, with a few tools in it, but after they say hello to Julia, they suddenly have two wheelbarrows out of the Rover and a lot of tools in both of them.

Other mistake: As Laura walks into a darkened bedroom, she turns the light switch on. Not only does the room light come on, but also the bedside lamps, just by turning the switch on by the door.

Plot hole: At the very end, Julia calls Matt, a policeman, at Helena's place, to tell him to come and help his mother and Rosemary who are being held against their will. But Matt doesn't have a mobile, so how did Julia know he was at Helena's place, so she could ring him there and save the day? No-one knew he was at Helena's and it's the middle of the night. Matt should have been in bed asleep.

Other mistake: When Rosemary comes back from seeing her old college professor, she comes in from the garden, but Julia's place - this is where Rosemary and Laura are staying - is on the first floor; there's no access to her place from the garden. Rosemary should have gone to the front door, on the street.

Plot hole: When Jeremy is found dead from a heart attack, for some reason, the girls talk about him taking something that caused his heart attack, or someone giving him something to cause his heart attack. People have heart attacks all the time, and Jeremy had "a dodgy ticker", so there's no reason for them to only think it's a "suspicious" heart attack.

Plot hole: While the girls are trying to work out who killed Jeremy, Rosemary says she thinks it's Julia - Julia owns the flat that Jeremy and Marcia live in - so Laura says "Why would she want Jeremy dead?" And Rosemary says "To sell the house for a greater amount of money." But that's wrong: When someone dies in a house, the house sells for less, not more - not many people want to live in a deceased estate.
