The United States teeters on the edge of war. The roundup of allegedly treasonous Japanese Americans is about to begin. And in L.A., a Japanese family is found dead. Murder or ritual suicide? The investigation will draw four people into a totally Ellroy-ian tangle: a brilliant Japanese American forensic chemist; an unsatisfiably adventurous young woman; one police officer based in fact (William H. "Whiskey Bill" Parker, later to become the groundbreaking chief of the LAPD), the other the product of Ellroy's inimitable imagination (Dudley Smith, arch villain of The Big Nowhere, L.A. Confidential, White Jazz). As their lives intertwine, we are given a story of war and of consuming romance, a searing exposé of the Japanese internment, and an astonishingly detailed homicide investigation. In Perfidia, Ellroy delves more deeply than ever before into his characters' intellectual and emotional lives. But it has the full-strength, unbridled story-telling audacity that has marked all the acclaimed work of the Demon Dog of American Crime Fiction.

    But darkness brings death and Hercule Poirot has to untangle family strife, love and suspicious visitors tangle in order to clarify the murderer and prevent disaster.

    There must be a victim. A suspect. A detective. The rest is just shuffling the sequence. Expanding the permutations. Grant McAllister, a professor of mathematics, once sat down and worked them all out – calculating the different orders and possibilities of a mystery into seven perfect detective stories he quietly published. But that was thirty years ago. Now Grant lives in seclusion on a remote Mediterranean island, counting the rest of his days.Until Julia Hart, a sharp, ambitious editor knocks on his door. Julia wishes to republish his book, and together they must revisit those old stories: an author hiding from his past, and an editor, keen to understand it.But there are things in the stories that don’t add up. Inconsistencies left by Grant that a sharp-eyed editor begins to suspect are more than mistakes. They may be clues, and Julia finds herself with a mystery of her own to solve.
