Number 91 bus. Tottenham Lane to Whitehall. But most importantly, Kings Cross St. Pancras to HMP Pentonville. Home. Not the prison. But close.

It’s 2021 and you’ve just got off the Eurostar. You’re on the bus because you’re lazy and tired. It’s a 28 minute walk you’ve taken a hundred times but today you’d just like to sit and look at it.

There’s a green ribbon tied to the nobbly pole of the routemaster. It’s tied in a bow. There’s the remains of a meat pie on the floor and someone’s left their shopping. You peer inside. It’s some shampoo (Timotei), a big issue, and a caramac.
