You will, of course, want to see what I did with the doorknob that I bought in Nottinghill when I visited this spring. I hung it in my kitchen beneath the painting of the coffee cup. Some mornings, as I sit at the breakfast table with my tea and toast, I imagine I can just turn that handle and walk through into Westminster. Sigh.
Perhaps I will find a spare tesseract or mislaid Babylon candle when I go down to clean the basement.
