As the film adaptation of Dan Brown's fourth Robert Langdon novel, Inferno, is released, we present this appreciation of the author by Michael Deacon from 2013.

Renowned author Dan Brown woke up in his luxurious four-poster bed in his expensive $10 million house – and immediately he felt angry. Most people would have thought that the 48-year-old man had no reason to be angry. After all, the famous writer had a new book coming out. But that was the problem. A new book meant an inevitable attack on the rich novelist by the wealthy wordsmith’s fiercest foes. The critics.

Renowned author Dan Brown hated the critics. Ever since he had become one of the world’s top renowned authors they had made fun of him. They had mocked bestselling book The Da Vinci Code, successful novel Digital Fortress, popular tome Deception Point, money-spinning volume Angels & Demons and chart-topping work of narrative fiction The Lost Symbol.

The critics said his writing was clumsy, ungrammatical, repetitive and repetitive. They said it was full of unnecessary tautology. They said his prose was mired in a sea of mixed metaphors. For some reason they found something funny in sentences such as “His eyes went white, like a shark about to attack.” They even say my books are packed with banal and superfluous description, thought the 5ft 9in man. He particularly hated it when they said his imagery was nonsensical. It made his insect eyes flash like a rocket.
