Los Angeles. December, 1941. America stands at the brink of World War II. War fever and racial hatred grip the city.

The hellish murder of a Japanese family summons three men and one woman. LAPD captain William H. Parker is superbly gifted, corrosively ambitious, liquored-up, and consumed by dubious ideology. He is bitterly at odds with Sergeant Dudley Smith--Irish émigré, ex-IRA killer, fledgling war profiteer. Hideo Ashida is a police chemist and the only Japanese on the L.A. cop payroll. Kay Lake is a twenty-one-year-old dilettante looking for adventure. The investigation throws them together and rips them apart. The crime becomes a political storm center that brilliantly illuminates these four driven souls--comrades, rivals, lovers, history's pawns.

Here, Ellroy gives us the party at the edge of the abyss and the precipice of America's ascendance. Perfidia is that moment, spellbindingly captured.
