About Mia: this storyline it is full of holes. Not huge in each case, but they add up, for me.
For a start, Clarrie said Jim brought the money round "first thing", when presumably Mia wasn't in the house -- she sleeps in Greenwood Cottage not Grange Farm. And it was gone when Clarrie next went home. So when exactly did Mia take it? Would she have been there after school when Clarrie and Emma were out?
And then there is Poppy's hair. A couple of weeks ago Mia was saying she had to spend her money to take Poppy to have her hair cut by the person Nic had it done by, but today she was having to plait Poppy's hair. So it is long and needing plaits, or short and needing to be cut by the special hairdresser.
And then there is doing all the shopping, only she doesn't: Will does it on line, as we know because of the time Ruairi gave her a lift home on his bike so she would be in when it was delivered. If he forgets something (like the pickles) he immediately takes the blame for it. Mia sometimes gets one thing from the shop, but that's not "all the shopping".
And he does at least some of the housework, because we heard about the pickle when he was making sandwiches.
And why didn't silly Mia leave a note: "Dear Granny, I borrowed some money so Poppy could go on a school trip, I'll pay you back" isn't that hard to write, is it? And she borrowed it on 29th, and was talking to Clarrie on 28th and said she had tried to tell her about the trip then, so she could have mentioned it at some point when they were not being interrupted by Clarrie not listening to her. They must have been together for a couple of hours at least and alone together for quite a lot of that while they got the teas ready.
It doesn't quite hang together, somehow.
