Matt, can I just say I'm really loving being on this holiday with you.

It is great fun and I feel like we kind of enjoyed doing the same things. Yeah, totally. I just feel like maybe we've done all the things you want to do though. I don't think that's true. You seem to have been enjoying yourself. Well, we did just spend all of yesterday watching five concurrent football games from the ball pool. You were loving it. Okay, well, I just want to mix it up a bit.

Okay.

So how do you feel about renting some of those jet skis?

I've had spinal surgery.

There's absolutely no way I'm doing something like that.

Okay, that makes a lot of sense. But water, that's good for taking pressure off the old Beck.

What about Shark Cage? Alice, are you trying to get me killed? There's just no way I'm taking a risk like that. Okay, maybe we just do baby steps. We could go to breakfast a little bit later than 6am, even though they might have run out of mini quassons. Are you mad? You end up at breakfast date.

They run out of many quassons. Then you don't have the nutrition you need to get you through the day. You end up sleep deprived, ill. And then if everyone's doing that, society crumbles. There's no order. And then what's the point in living in a democracy? That is a risk I'm not prepared to take. Book the Shark Cage.

2011, Shrewsbury, Shropshire.

57-year-old Alan Bates hurries along the busy high street.

Zips up his waterproof and glances behind him.

His heart thumps. The man's still there.

A few days back, he received a mysterious call from someone claiming they had explosive information about the post office horizon system. For eight years, Alan's been at war with the post office,

fighting to clear the names of sub-postmasters falsely accused of stealing.

And sub-postmasters are in charge of those branches. They're basically the franchisee.

Exactly. So they're the people when you take in the wrong QR code to return your parcel.

They're the people whose Thursday afternoon is being ruined.

He's taken on a powerful billion-pound company, and they're determined to shut him down.

He risks another glance at the figure following him, takes a mental picture, short grey hair, dark framed glasses.

Alan ducks quickly into a cafe, hoping to lose him.

But the man's right there.
