Katy, aka Bloodline, is our juv lead. She’s young, gifted and beautiful. Let alone to the manner born. And as for that voice of hers, it’s vintage, tawny port made audible. (The quality and clarity and timbre of a guide’s voice – it’s something that often gets overlooked when people are selecting a tour; it shouldn’t be. Boy, are we ever aware of it. There are guides out there – none of them are London Walks guides, I hasten to add – listening to them is like listening to a paint scraper in action. NO. THANK. YOU.) And if you want to see Katy in action, well, a click here takes you to the little video trailer film maker Jon Klein’s made of her Village in Piccdilly Walk.
