Me: Where were you?
Nell: With Sally.
Me: Come and see the funny photos I took on our walk yesterday. It was so lovely to be out again.
Nell: Very nice.
Me: Look at the one of Kev and Harriet playing football. It’s a real action shot.
Nell: I’m not in the mood for photos.
Me: What’s the matter? Has something happened?
Nell: I’ve just had a rather worrying conversation with Sally.
Me: Oh dear. What about?
Me: I’m getting tired of moles, to be honest. Everything is about moles, or Mole Watching, at the moment.
Nell: This was about a very different kind of mole.
Me: There are bound to be lots of different species, Nell. Are we looking for a particular one?
Nell: Can I trust you?
Nell: Sally has a mole in the Beefy camp.
Me: Are we talking about informants now?
Nell: We are.
Me: We guessed that already and we know who it is, don’t we?
Nell: Yes, although we didn’t have all the facts.
Me: What do you mean?
Nell: The mole just told Sally that the Beefies have a mole in our camp too.
Me: Do you mean there’s someone here we trust who we shouldn’t trust?
Nell: I do.
Me: That’s shocking.
Nell: And Sally says that someone is about to arrive here with a mole.
Me: Our mole, or their mole?
Nell: A real mole. They’re going to claim they captured it.
Me: So our mole says their mole is going to bring us a real mole?
Me: How will we know the real mole is real?
Nell: Because it’s a mole. But that’s not the point.
Me: Isn’t it?
Nell: It will reveal the identity of their mole to us.
Me: Oh yes. Sorry.
