Today starts with a vintage railway poster and an early start. This is the end of the ‘ big birthday’ season, celebrating birthdays with an 0 with friends in interesting places. On this occasion we are the birthday surprise, so this will be published once we have revealed ourselves.

We are heading to floor 37 of the Shard, where I will be able to overlook my former workplace, which was just behind St Paul’s Cathedral.

Like all the big ‘0’ birthdays there has been much planning and some subterfuge. The denouement could be ruined by an overzealous hotel receptionist not allowing us to boldly walk up to a gentleman s bedroom door fearing that we are some unusually attired ‘ ladies of the night’. We will, of course, actually and accurately be ladies or indeed, women of the early morning.

Let’s of see how this goes.
