After completing the Harry Potter series, J.K. Rowling started writing a mystery series under the pseudonym Robert Galbraith. And happily, her virtuosic talent as a spinner of stories with intricate plots and singular characters is front and center again. Lethal White is the fourth in the Cormoran Strike series, and it’s perfectly narrated by Robert Glenister, who can ace a wonderfully wide range of British accents. In Lethal White, Strike, a London private investigator with a reputation for unraveling high-profile cases, and his able, lovely (yes, their attraction thrums below the surface) assistant, Robin, are in the thick of it, investigating political blackmail and the murder of a Tory minister, all wrapped in a blur of populist politics, replete with a wild cast that includes radical lefties, conservative snobs and a mentally ill young man who desperately wants Strike’s help. After this 22-hour treat, I can’t wait for Strike five.
