Peter Forbes has been awarded the Warwick Prize for Writing for his book Dazzled and Deceived: Mimicry and Camouflage.
The biennial prize, which is run and self-funded by the University of Warwick, was launched in 2009 and each winner receives GBP 50,000.
Forbes' book looks at mimicry and camouflage within the spheres of science, art and the natural world.
'The fact that the prize comes from an academic institution that has always championed imaginative writing and that the book was chosen by an exceptionally creative group of judges makes it all the more precious,' said Forbes, on receiving his award.
Also on the shortlist for the award were Nadeem Aslam for his book The Wasted Vigil, Aminatta Forna's The Memory of Love, and Peter D McDonald for his work The Literature Police: Apartheid Censorship and its Cultural Consequences.
