L'époque sera assez étendue apparemment :
"The four novels will be set in Los Angeles during the Second World War and will "seamlessly cohere" with the previous quartet and the more recent Underworld USA trilogy, the publisher said, taking major and minor characters from those books and spotlighting them as younger people. Together, the 11 novels will highlight 31 years of American history in "an unprecedented and ambitious manner"."

Il en parle en interview :
"The L.A. quartet (“The Black Dahlia,” “The Big Nowhere,” “L.A. Confidential,” “White Jazz”) covers Los Angeles between 1946 and 1958. The Underworld U.S.A. trilogy, (“American Tabloid,” “The Cold 6000,” “Blood’s A Rover”) covers America at large from ‘58 to ‘72. The second L.A. quartet, I’ve just begun the first volume, takes characters from the original trilogy and places in Los Angeles during World War II as significantly younger people. I’m writing the first novel now. It transpires solely within the month of December, 1941, the month the Japanese bombed Pearl Harbor."
