Charles Cumming was born in Scotland in 1971. He was educated at Eton and graduated from the University of Edinburgh in 1994 with First Class Honours in English Literature. The Observer has described him as "the best of the new generation of British spy writers who are taking over where John le Carré and Len Deighton left off". In the summer of 1995, Charles was approached for recruitment by the Secret Intelligence Service (MI6). A year later he moved to Montreal where he began working on a novel based on his experiences with MI6. A Spy By Nature was published in the UK in 2001. This is his fifth novel.
