'I've long wished perfumery to be taken seriously as an art, and for scent critics to be as fierce as opera critics, and for the wearers of certain "fragrances" to be hissed in public, while others are cheered. This year has brought Perfumes: The Guide by Luca Turin and Tania Sanchez, which I breathed in, rather than read, in one delighted gulp.' Hilary Mantel, Guardian Perfumes: The Guide is the culmination of Turin's lifelong obsession and rare scientific flair and Sanchez's stylish and devoted blogging about every scent that she's ever loved and loathed. Together they make a fine and utterly persuasive argument for the unrecognised craft of perfume-making. Perfume writing has certainly never been this honest, compelling or downright entertaining.

'Meet Luca Turin, a renegade scientist and perfume critic with an extraordinary sense of smell.' Newsday Funny, irreverent and passionate, The Secret of Scent opens the lid on two worlds - the glamorous and highly lucrative realm of the perfume makers, and the equally rivalrous domain of smell science. Smell is our forgotten sense. Long neglected by science in favour of more prestigious areas of research, it's also barely understood in general life. At the core of our sense of smell lies an enigma: why do things smell the way they do? How is smell written into the molecules? This book is the story of the quest to solve this puzzle. Luca Turin has been described in The Economist as 'a man with a powerful nose and a bizarre obsession with perfume.' Starting with a tour of the great perfumes and their gifted makers, he shows how few people have an idea of what perfume is or how it is made, let alone how smell works and what part it plays in other pleasures like food. But not everyone has ignored this powerful sense. A small band of mavericks has been trying to crack the code of smell for seventy years. Building on their work, Turin thinks he has succeeded. And like all good mysteries, the solution was all the while hidden in plain sight - in this case, right under our noses.

One man's passion for perfume leads him to explore one of the most intriguing scientific mysteries: What makes one molecule smell of garlic while another smells of rose?

In this witty, engrossing, and wildly original volume, author Luca Turin explores the two competing theories of smell. Is scent determined by molecular shape or molecular vibrations? Turin describes in fascinating detail the science, the evidence, and the often contentious debate—from the beginnings of organic chemistry to the present day—and pays homage to the scientists who went before.

With its uniquely accessible and captivating approach to science via art, The Secret of Scent will appeal to anyone who has ever wondered about the most mysterious of the five senses.
