To a childhood friend, he’s Bunsen. To his sister, he’s Stick. To the colleague whose life he saved, he’s Bob, and to his ex-fiancee, he’s Bluey. In the US, they know him as C.B. Strike, but in the UK, he’s Cormoran Strike, a Cornish PI operating out of Soho’s Denmark Street. He’s the star of five detective novels by Robert Galbraith (an alias of J.K. Rowling), and he’ll soon be back on BBC One starring in his fifth miniseries Strike: Troubled Blood. As it’s been over two years since we last saw Cormoran and his agency partner Robin Ellacott in the Strike: Lethal White finale, here’s a refresher on what we need to remember from last time around.

Robin and Matthew: the Wedding and the Divorce

In the final moments of Career of Evil, Robin said ‘I do’ to her long-time boyfriend Matthew, despite having learned that he’d cheated on her with a colleague – Sarah – years earlier when she was suffering from the aftermath of her university attack. After firing Robin for endangering the case by pursuing a lead solo, Strike raced to her Yorkshire wedding and made it just before the couple exchanged vows. Seeing Strike at the back of the church, Robin smiled and married Matthew.

Who Killed Jasper Chiswell in Lethal White?

We attempt to untangle the convoluted plot here. In short: it was Jasper’s illegitimate son Raphael (Raff). Raff had seduced his step-mother Kinvara and convinced her to collude in the old man’s murder – ostensibly because he loved and wanted to be with her, but really so that he could get his hands on a family painting the value of which only he recognised as worth over 20 million. Jasper disliked Raff and had disinherited him, so Raff started an affair with Kinvara and planned to marry her after Jasper’s death and then kill her a year or so later by staging a riding accident, meaning he inherited the valuable painting through her. Together, they concocted a plan to spike Jasper’s morning orange juice and create a false alibi for Kinvara, but Strike and Robin untangled their web of lies, leading to a confrontation with a gun on a narrow boat, that thankfully everybody who matters survived unscathed.

How Strike and Robin Met

By chance. Robin was assigned to Strike’s Denmark Street office for a week of agency temping as his assistant, but soon found a taste and a talent for the work of a private investigator. In the first series, she successfully interviewed for a much higher-paying HR job in a bland city firm, but chose not to take them up on their offer, finding more satisfaction in Strike’s world, despite the disapproval of her then fiancé and now soon-to-be ex-husband Matthew. 

How Strike Became a Private Investigator

After his mother’s death, he dropped out of Oxford university, where he started dating his former fiancée Charlotte Chapman, and joined the army. After losing his lower leg in an explosion in Afghanistan, he transferred to SIB (Special Investigation Branch) and worked as a military police officer, before using those skills to set up his Soho detective agency. 

Robin’s Panic Attacks and Dropping Out of University

Mid-way through a degree in psychology, Robin was the victim of an assault on campus by a serial perpetrator wearing a gorilla mask. She gave evidence that led to his conviction for rape and attempted murder, and the trauma led to her dropping out of university and moving back home with her parents. The trauma left her with panic attacks, which she kept secret from Strike until she suffered one while driving them both in series 4, Lethal White, and was forced to tell him.

Strike and Charlotte

Only fragments are known in the TV series. Before the series began, Cormoran was engaged to socialite Charlotte Chapman (Peaky Blinders‘ Natasha O’Keeffe). When he first met Robin, he was mid-argument with Charlotte, who stormed out of his office promising that, like always, he would come crawling back to her. Cormoran moved out of their place and started sleeping in his Denmark Street office, where Charlotte sent his possessions in a box marked ‘Arsehole’. 

Cormoran Strike’s Parents

Rock star Jonny Rokeby, whom we’ve never met in the series, and model/ ‘groupie’ Leda Strike. Rokeby is a famed womaniser who fathered several children and is largely absent in their lives (‘As far as Johnny Rokeby was concerned, I was just a shuddering of loins’), giving Cormoran multiple half-siblings. Leda was a supermodel who died of a heroin overdose that Strike has always suspected was administered deliberately by her second husband, musician Jeff Whittaker (Matt King). 

Strike’s Brothers and Sisters

There are seven in total in the books, but we’ve only met two on screen – Lucy on his mother’s side and Al on his father’s, but the ‘Rokeby diaspora’ as Al wryly describes them, are scattered all over. 

How Strike Lost His Leg

Serving in Helmand Province, Afghanistan. His convoy drove into an ambush in which an IED explosion killed several of his colleagues and lost Strike the lower half of one leg. He wears a prosthetic, but the injury means he’s unable to drive and generally less able to pursue suspects on foot than Robin. 

Past Cases

Who Killed Teenager Kelsey Platt in Career of Evil?

Donald Laing (Neil Maskell), who bore a deadly grudge against Strike after he put him away years ago for the murder of his wife. After serving his sentence, Laing stole from and killed a neighbour, then stole the identity of Ray Williams, an ex-firefighter who’d emigrated, and ingratiated himself into the family of teenager Kelsey Platt, who harboured a crush on Cormoran Strike. To get revenge on Strike, Laing lured Kelsey to a London location where he killed and dismembered her, posing as a new client to make Strike visit the same location and frame him for the murder. Laing posted one of Kelsey’s legs to Robin at Strike’s office, along with lyrics from Strike’s mother’s favourite song by Blue Oyster Cult, in order to goad him. Strike realised that Ray Williams and Donald Laing – who pretended to suffer from debilitating arthritis, and was therefore ruled out as a suspect in Kelsey’s murder – were one and the same, under a wig, false beard and coloured contact lenses. 

Who Killed Novelist Owen Quine in The Silkworm?

His agent Liz Tassel (Lia Williams). Decades earlier, Liz was in love with fellow writer Andrew Fancourt (Peter Sullivan) and wrote a hurtful parody, which was published anonymously, of his wife’s novel. She spread rumours that Fancourt had written the parody himself, and his wife killed herself over it. Liz’s client Owen learned that she was behind the parody, and blackmailed her about it for years, forcing her to keep him on as a client over the much more successful and celebrated Andrew Fancourt. When Owen submitted a manuscript to Liz that was intended to spill the dirty secrets of the publishing world under a fantasy allegory (including her humiliating attempt to seduce Fancourt), she edited the manuscript to keep her secrets and sent it out to everybody it was based on. She told Owen to stage a public fight with her about it, then hide out in an old house to generate publicity for the sale of the book. In hiding, she murdered him in the same manner that the hero dies in his manuscript, stopping the blackmail once and for all.
