In recent weeks, I’ve had my head down, writing my new book, but I have occasionally done the odd bit of filming – remarking, in my new role as royal-historian-turned-commentator, on William and Kate’s (sorry – the Duke and Duchess of Cambridge’s) visit to Canada for CTV, and here, back on much more familiar ground, talking about Elizabethan progresses with Griff Rhys Jones for a new BBC series. Griff is following Elizabeth I’s progress of 1574 in the modern-day luxury equivalent of Elizabethan splendour: a Rolls Royce Phantom Five. I could happily sit in the back of this car, talking history, and call it work every day! But alas, the library beckons… (you know I don’t really mean that!)
