Once you see, you can never unknow it.
The clues are there. No one could read them. Until now.
London is full of secrets but this one is the biggest. All it needed was for someone to join up the dots.
This isn't about Dan Brown. You don't need to believe in anything. Just be ready to notice what's hidden in plain sight.
On Grail Trail, you'll take a fresh look at its pub signs, its street names, its ancient carved stonework — and learn how to decode their hidden meanings. Atmospheric, mind-expanding and packed with genuine historical revelation, GrailTrail shows you a London you've never seen before. By the time you finish, you'll be fluent in geomancy and the many mystic signs that fill the City. And you'll never walk past them again without knowing exactly what they mean.
