Robert Galbraith

Robert Galbraith is the pseudonym under which J.K. Rowling — born Joanne Rowling in Yate, England, in 1965 — writes her Cormoran Strike crime fiction series. The name was chosen deliberately: Robert after Robert F. Kennedy, a personal hero, and Galbraith from a name she had invented for herself in childhood. The intention from the outset was to step away from one of the most famous bylines in publishing history and be judged purely on the work.

Before the Strike novels existed, Rowling had already reshaped children's literature with the seven-volume Harry Potter series, one of the best-selling book series ever published, and had made her first foray into adult fiction with The Casual Vacancy in 2012, a sharp, darkly comic novel about small-town English politics. Crime fiction, though, was a genre she had loved as a reader for years. Writing it under a pseudonym gave her something rare: the chance to start over, without hype or expectation, and to receive unvarnished feedback on her craft in a new form.

The Cuckoo's Calling, published in April 2013, introduced readers to Cormoran Strike — a one-legged Afghanistan veteran turned private detective, working out of a cramped office above a Denmark Street guitar shop in London — and his resourceful assistant, Robin Ellacott. Initially, the novel sold modestly, attracting good reviews but little wider attention. That changed when a journalist uncovered the pseudonym and the secret became public. Sales surged, and Rowling's authorship was confirmed. She has written under the Galbraith name ever since, keeping the imprint distinct from her other work so that readers know precisely what a Cormoran Strike novel promises.

The series has grown steadily across eight novels: The Cuckoo's Calling (2013), The Silkworm (2014), Career of Evil (2015), Lethal White (2018), Troubled Blood (2020), The Ink Black Heart (2022), The Running Grave (2023), and The Hallmarked Man (2025). A ninth novel, Sleep Tight, Evangeline, was announced in February 2026. As of early 2024, the series had sold more than 20 million copies worldwide and been translated into 43 languages across more than 50 countries.

Each novel presents a self-contained case — a suspicious death, a missing person, a gruesome discovery — while the personal lives of Strike and Robin develop across the series in ways that reward readers who follow from the beginning. The books are long by genre standards, and deliberately so. The author has spoken of knowing far more about her characters than ever appears on the page, building their histories and contradictions with the same layered attention she brings to plotting. Social concerns run throughout: domestic violence, class, addiction, misogyny, and the mechanics of how institutions fail people all surface across the series without ever overwhelming the central mystery.

Troubled Blood, the fifth instalment, won the Crime and Thriller Book of the Year Award. The television adaptation, titled Strike, began airing on BBC One in 2017, starring Tom Burke as Cormoran Strike and Holliday Grainger as Robin Ellacott, and was picked up by HBO for distribution in North America. The production has run to multiple seasons, bringing a new audience to the books.

Writing as Galbraith has remained, by the author's own account, one of the most creatively satisfying parts of her career — a space defined by the work itself rather than the surrounding noise. The Cormoran Strike series stands as one of the most commercially successful and critically engaged crime fiction enterprises in contemporary British publishing, with no sign of slowing.
