Professor Anthony Kessel has a double life – or at least two very different roles. As the National Deputy Medical Director of NHS England, he’s one of the senior leaders responsible for improving the quality of our health services and patient care. He’s an international authority on public health and played a key role in the NHS’s response to the Covid pandemic. He’s also a writer, with a prize-winning series of detective novels for young adults called Don’t Doubt the Rainbow – the most recent is American Mystery. The books are adventure stories and also aim to give young readers insights into how the mind works, and to improve their psychological well-being. Anthony's music choices include Brahms, Dvořák, Astor Piazzolla and Chilly Gonzales.
