“The Emperor of Ocean Park” is set in two privileged worlds: the upper-crust African American society of the eastern seaboard — old families who summer on Martha’s Vineyard — and the inner circle of an Ivy League law school. It tells the story of a complex family with a single, seductive link to the shadow lands of crime.

The emperor of the title, Judge Oliver Garland, has just died, suddenly. A brilliant legal mind, conservative and famously controversial, Judge Garland made more enemies than friends. Many years before, he’d earned a judge’s highest prize: a Supreme Court nomination. But in a scene of bitter humiliation, televised across the country, his nomination collapsed in scandal. The humbling defeat became a private agony, one from which he never recovered.

But now the judge’s death raises even more questions  and it seems to be leading to a second, even more terrible scandal. Could Oliver Garland have been murdered? He has left a strange message for his son Talcott, a professor of law at a great university, entrusting him with “the arrangements”  a mysterious puzzle that only Tal can unlock, and only by unearthing the ambiguities of his father’s past. When another man is found dead, and then another, Talcott — wry, straight-arrow, almost too self-aware to be a man of action — must risk his career, his marriage and even his life, following the clues his father left him.

Walter Mosley is the author of the acclaimed Easy Rawlins mystery series, the novels “Blue Light” and “RL’s Dream,” a collection of stories featuring Socrates Fortlow (“Always Outnumbered, Always Outgunned,” for which he received the Anisfield-Wold Award) and “Walkin’ the Dog.” He was born in Los Angeles and lives in New York.

His new novel finds narrator Paris Minton and his friend Fearless Jones in Los Angeles in the 1950s with few rights and no money. While searching for Paris’ mysterious lover, Elana Love, they find themselves fighting their way out of a steadily growing, bewildering vortex of betrayal and violence.

“Abandoning the voice of his premier creation, Easy Rawlins, Mosley mines a new shaft of 1950s Los Angeles with a hero who combines the principles of Easy with the deadliness of Ray ‘Mouse’ Alexander. The result is a violent, heroic and classic piece of noir fiction.” — Publishers Weekly
