Plot overview

Novels and novellas

Rivers of London  
(American Title: Midnight Riot)

The novel centres on the adventures of Peter Grant, a young officer in the Metropolitan Police; who, following an unexpected encounter with a ghost, is recruited into the small branch of the Met that deals with magic and the supernatural.

Peter Grant, having become the first English apprentice wizard in over seventy years, must immediately deal with two different but ultimately inter-related cases. In one he must find what is possessing ordinary people and turning them into vicious killers, and in the second he must broker a peace between the two warring gods of the River Thames and their respective families.

Moon over Soho 

Following the events of Rivers of London Police Constable and apprentice wizard Peter Grant is called in to help investigate the brutal murder of a journalist in the downstairs toilet of the Groucho Club in London's Soho district. At the same time Peter is disturbed by a number of deaths of amateur and semi-professional jazz musicians that occurred shortly after they performed. Despite the apparently natural causes of death each body exhibits a magical signature which leads Peter to believe that the deaths are far from natural.

Whispers Under Ground 

The son of a US senator is stabbed to death, and magic involvement is suspected. An FBI agent is involved with DC Grant's case. Meanwhile, in the sewers near the tunnels of London's Underground, something is happening.

Broken Homes 

Another killer is on the loose, and the prime suspect could be an associate of the twisted magician known as the Faceless Man. A town planner goes under a tube train, and a grimoire has been stolen. And when Peter gets word of something very odd happening in Elephant and Castle, he has to investigate whether there is a connection.

Foxglove Summer 

Leaving London, Peter goes to a small village in Herefordshire, where there appears to be a supernatural element to the disappearance of two local girls. Having to cope with local cops, as well as local gods, Peter finds the mystery deepens.

The Hanging Tree 

Back in London, Peter faces the legacy of London's hangings. Investigating suspicious murders in the world of the super-rich, Peter is in a different world to the one he is used to investigating.

Other work 
Aaronovitch has also announced several works within the same fictional universe, but set outside the chronology of the main series. These works include a short story entitled 'Cock of The Wall' focusing on Petrus Aelius Bekemetus, who Aaronovitch describes as a "temple official/Londinium wideboy" - i.e. set in Roman London which Peter Grant briefly visited in the first book of the series. Also planned is an untitled Novella focusing on Peter's mentor Thomas Nightingale.  
On 1 May 2019 it was announced that a television adaptation of Rivers of London would be produced by Simon Pegg and Nick Frost's production company, Stolen Picture.
At Dragonmeet convention in London, on 30 November 2019, it was announced that a role-playing game based on the book series would be published by Chaosium.

Stories listed by internal chronology 
In a blog entry, the author has provided a list of the stories, by internal chronology.

On the page where the official order is given, the author writes: "One caveat - the short story The Home Crowd Advantage is obviously set in 2012 during the London Olympics but because it was written before the chronology of the series had firmed up it contains a number of anachronisms. I've learnt to be philosophical about this sort of thing." Many of the stories give vague dates, and some of those dates conflict with the official series order (compare Foxglove Summer and The Furthest Station).
