Detective Inspector Declan Walsh

It's a time of change for the Last Chance Saloon—recent promotions have changed the focus of the Unit, and when a Fleet Street Legend, Hunt Robinson, is kidnapped from Heathrow Airport and found close to death in the crypt of Fleet Street's St Bride's Church, DI Declan Walsh and his colleagues need to put the past behind them, and unite to take on the case.

Following the bombshell ending of Kill Your Darlings, Declan Walsh has a new job, a new office and a new remit—but when a City of London art gallery discovers the star of their latest exhibition dead, with only a signed, painted "kiss" on his neck to go on, Declan and his team must investigate a murder that involves brutal vengeance, a family linked to a painting stolen by the Nazis in WW2, and a long-forgotten promise.

When a body is found beside the Roman Fort Gate on the London Wall, dressed as a Roman Soldier and with an antique Roman Gladius stabbed into their chest, it's tasked to DCI Declan Walsh and the team of the Last Chance Saloon to investigate the murder, leading them into a rabbit hole of similarly themed attacks - as re-enactors perform real-life battles at various locations for a "History of London" celebration during the day, with some taking a darker and more brutal approach at night.

When new victims of the still-at-large serial killer known as the Red Reaper start to appear in London, DCI Declan Walsh and his team are placed back on the case—but everything isn't what it seems. For a start, the deaths are different, and the calling card is new. It could be a copycat, apart from one thing... They know what Declan did to the real Red Reaper a year earlier. Something only Declan and the closest members of his team keep secret. Is this the real Reaper, back to gain revenge on Declan and his family—or is this a protégé, staking his own claim to the serial killer name?

Someone is killing London "black cab" taxi drivers. Seemingly unconnected, but all with the same MO, bodies are being found across the City of London, and only two clues connect them; an unknown killer with a crooked walking cane, and the title to a folk song placed on rolled paper inside their mouths. Now, DCI Walsh and his team, still reeling after the end of Harvest For The Reaper must hunt down the killer.

Three years ago, Detective Sergeant Anjli Kapoor faced her most terrifying case—the brutal kidnapping and murder of two young girls, each found with posies in their pockets. The prime suspect, local florist Thomas Blackthorne, committed suicide, leaving the case unresolved and haunting Anjli ever since. Now, history seems to be repeating itself. Another child has vanished, with all signs pointing to the same twisted killer. But how can it be, when the prime suspect is dead?
