Andy McNab joined the infantry as a boy soldier. In 1984 he was 'badged' as a member of 22 SAS Regiment and was involved in both covert and overt special operations worldwide. During the Gulf War he commanded Bravo Two Zero, a patrol that, in the words of his commanding officer, 'will remain in regimental history for ever'. Awarded both the Distinguished Conduct Medal (DCM) and Military Medal (MM) during his military career, McNab was the British Army's most highly decorated serving soldier when he finally left the SAS in February 1993. He wrote about his experiences in two phenomenal bestsellers, Bravo Two Zero, which was filmed in 1998 starring Sean Bean, and Immediate Action. He is the author of the bestselling novels, Remote Control, Crisis Four, Firewall, Last Light, Liberation Day, Dark Winter, Deep Black and Aggressor. Besides his writing work, he lectures to security and intelligence agencies in both the USA and UK. Robert Rigby began his career as a journalist, then spent several years in the music business as a songwriter and session musician. He turned to writing for radio, television and the theatre and has also directed and performed in children's theatre throughout the country. He has become an established young people's playwright and his award-winning work with youth theatre companies has been seen in Britain, Europe, the USA and Africa. He wrote the novelizations of the movies, Goal! and Goal II, and his scripts include the long-running BBC children's drama series Byker Grove.
