Many visitors to Britain like to partake in the ritual of afternoon tea, which is a long-standing British tradition. It combines the British love of drinking tea with a fondness for cakes and other sweet dishes in the middle of the afternoon. Many hotels and well-known shops, such as Fortnum and Mason on Piccadilly, offer afternoon tea packages.

I’ve taken my cue from an erstwhile neighbour – Alfred Hitchcock was born just up the road in Leytonstone – and I’ve moved to the rear window. I’m in search of the colour purple. But instead of the lilac that coyly shows its first blush this time of year through the satin-white of the magnolia tree and the billowing chartreuse of the willow, I’m getting a Phoenician purple that would have turned Queen Elizabeth I, who banned the royal colour from her court, apoplectic.
