Joseph Wambaugh did not invent the police novel, but no one had seen anything like 'The New Centurions' when it was published in 1971. Here was a working, living, breathing cop with a decade of experience on the beat.

Film rights were in the offing for 'The Onion Field,' eventually made into a movie in 1979; 'The New Centurions' became a 1972 film starring George C. Scott, while 'The Blue Knight' starred William Holden in a 1973 mini-series version.

Wambaugh's naturalistic portrait of the cop world turned 'Centurions' and 'The Blue Knight' (1972) into bestsellers, but his next two books made him relevant to a larger audience and to the next generation of crime writers.
