During the latest interview for her channel, the Duchess highlighted the importance of reading as a form of therapy.

She said: “However difficult things are, you can get away from them and go into your own world for a bit. Just take yourself away from everything that’s annoying you and read a book. I think it’s the most therapeutic thing you can do.

“After lockdown, especially, when we were all in a world we didn’t understand. What better than to reach for a book?”

But there’s one novel the Duchess admits going back to “time-and-time again”.

When asked what her “desert island book” would be, she replied: “Elizabeth Jane Howard’s ‘The Cazalet Chronicles’. I love a saga and they’re so beautifully written. I think she is a very underestimated writer. I’ve read them I don’t know how many times.”

But the Duchess admitted she was left devastated when – after writing to Howard to ask for a sequel – the author died.

She added: “It was the saddest thing. You’re slightly left hanging, she never really completed them. Sometimes I wonder if another author will come in and finish them off.”
