India, March 18 -- Len Deighton, a prolific writer whose tough, stylish spy thrillers featured on bestseller lists for decades, has died. He was 97. Deighton's literary agent, Tim Bates, said he died on Sunday. No cause of death was given. Deighton's first novel, "The IPCRESS File," helped set the tone of cool and gritty 1960s thrillers and was made into a film starring Michael Caine that helped launch both author and actor to long and stellar careers. Born to a working-class family in a wealthy part of London in 1929 - his father was a chauffeur and his mother a part-time cook - Deighton grew up with a keen eye for the intricacies and absurdities of Britain's class system.
