Published under a pseudonym, J. K. Rowling's brilliant debut mystery introduces Detective Cormoran Strike as he investigates a supermodel's suicide in "one of the best books of the year" (USA Today), the first novel in the brilliant series that inspired the acclaimed HBO Max series C.B. Strike.
Rest of description
After losing his leg to a land mine in Afghanistan, Cormoran Strike is barely scraping by as a private investigator. Strike is down to one client, creditors are calling, and after a breakup with his longtime girlfriend, he's living in his office.
Then John Bristow walks through his door with a shocking story: His sister, the legendary supermodel Lula Landry -- known to her friends as the Cuckoo -- famously fell to her death a few months earlier. The police ruled it a suicide, but John refuses to believe that. The case plunges Strike into the world of multimillionaire beauties, rock-star boyfriends, and desperate designers, and it introduces him to every variety of pleasure, enticement, seduction, and delusion known to man.
You may think you know detectives, but you've never met one quite like Strike. You may think you know about the wealthy and famous, but you've never seen them under an investigation like this.
Private investigator Cormoran Strike must track down a missing writer -- and a sinister killer bent on destruction -- in this "wonderfully entertaining" mystery (Harlan Coben, New York Times Book Review) that inspired the acclaimed HBO Max series C.B. Strike.
When novelist Owen Quine goes missing, his wife calls in private detective Cormoran Strike. At first, Mrs. Quine just thinks her husband has gone off by himself for a few days -- as he has done before -- and she wants Strike to find him and bring him home. But as Strike investigates, he discovers that Quine's disappearance is no coincidence. The novelist has just completed a manuscript featuring poisonous pen-portraits of almost everyone he knows. If the novel were published, it would ruin lives -- meaning that almost everyone in his life would have motives to silence him. When Quine is found brutally murdered under bizarre circumstances, Strike must race against time to understand the motivation of a ruthless killer, a killer unlike any he has encountered before . . . A compulsively readable crime novel with twists at every turn, The Silkworm is the second in J. K. Rowling's highly acclaimed series featuring Cormoran Strike and his determined young assistant, Robin Ellacott.
A disturbing package leads Detective Cormoran Strike and his assistant Robin Ellacott to investigate four dangerous murder suspects in this "magnetic" British mystery (Michiko Kakutani, New York Times) that inspired the acclaimed HBO Max series C.B. Strike. When Robin Ellacott opens an unexpected delivery, she is horrified to discover that it contains a woman's severed leg. Her boss, private detective Cormoran Strike, is less surprised but just as alarmed. He suspects that four people from his past could be responsible -- and any one of them is capable of sustained and unspeakable brutality. With the police focusing on the one suspect Strike has essentially ruled out, he and Robin take matters into their own hands and delve into the dark and twisted worlds of the other three men. But as more horrendous acts occur, time is running out for the two of them . . . Career of Evil is the third in J. K. Rowling's highly acclaimed series featuring private detective Cormoran Strike and his assistant Robin Ellacott. A fiendishly clever mystery with unexpected twists around every corner, Career of Evil is also a gripping story of a man and a woman at a crossroads in their personal and professional lives.
An unsettling cold case investigation ensnares Cormoran Strike and his partner in a web of dangerous secrets in this #1 New York Times bestseller, the inspiration for HBO Max's acclaimed series C.B. Strike.
When a troubled young man named Billy asks Cormoran Strike to help him investigate a crime he witnessed as a child, the private eye is left deeply troubled. While Billy is obviously mentally distressed and cannot remember many concrete details, there is something sincere about him and his story. But before Strike can question him further, Billy bolts from his office in a panic.
Trying to get to the bottom of Billy's story, Strike and Robin Ellacott -- once his assistant, now a partner in the agency -- set off on a twisting trail that leads them through the backstreets of London, into a secretive inner sanctum within Parliament, and to a beautiful but sinister manor house deep in the countryside. And during this labyrinthine investigation, Strike's own life is far from straightforward. His newfound fame as a private eye means he can no longer operate behind the scenes as he once did. Plus, his relationship with his former assistant is more fraught than it ever has been; Robin is now invaluable to Strike in the business, but their personal relationship is much, much trickier than that. The most epic Robert Galbraith novel yet, Lethal White is "addictive, murderous fun" for British mystery lovers and crime fiction fans alike (Vox).
In the epic fifth installment in this “compulsively readable” (People) series, Galbraith’s “irresistible hero and heroine” (USA Today) take on the decades-old cold case of a missing doctor, one which may be their grisliest yet.

Rest of description
"Outrageously entertaining." —Financial Times
Private Detective Cormoran Strike is contacted by a worried father whose son, Will, has gone to join a religious cult in the depths of the Norfolk countryside.
The Universal Humanitarian Church is, on the surface, a peaceable organization that campaigns for a better world. Yet Strike discovers that beneath the surface there are deeply sinister undertones, and unexplained deaths.
In order to try to rescue Will, Strike's business partner, Robin Ellacott, decides to infiltrate the cult, and she travels to Norfolk to live incognito among its members. But in doing so, she is unprepared for the dangers that await her there or for the toll it will take on her ...
Utterly page-turning, The Running Grave moves Strike's and Robin's story forward in this epic, unforgettable seventh installment of the series.
A dismembered corpse is discovered in the vault of a silver shop. The police initially believe it to be that of a convicted armed robber - but not everyone agrees with that theory. One of them is Decima Mullins, who calls on the help of private detective Cormoran Strike as she's certain the body in the silver vault was that of her boyfriend - the father of her newborn baby - who suddenly and mysteriously disappeared.
The more Strike and his business partner Robin Ellacott delve into the case, the more labyrinthine it gets. The silver shop is no ordinary one: it's located beside Freemasons' Hall and specializes in Masonic silverware. And in addition to the armed robber and Decima's boyfriend, it becomes clear that there are other missing men who could fit the profile of the body in the vault.
As the case becomes ever more complicated and dangerous, Strike faces another quandary. Robin seems increasingly committed to her boyfriend, policeman Ryan Murphy, but the impulse to declare his own feelings for her is becoming stronger than ever.
A gripping, wonderfully complex novel which takes Strike and Robin's story to a new level, The Hallmarked Man is an unmissable read for any fan of this unique series.
