We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns, the ones we don’t know we don’t know.

On board Challenges

We began our Spy tour of London covering all of central Londons key sights, the guide was very knowledgable pointing out all the sights and letting us into the secrets of Londons undercover spy world through out the ages.

I would throughly recommend this tour, as in effect you have a sightseeing tour as well as a Spy tour, so my advice is climb aboard.
