The order the books were released — the default way to read the series.
The DI Nikki Galena series follows a driven, rule-bending detective inspector leading a small unit investigating violent crime and organised gangs across the fictional Fenland town of Greenborough and the flat, dyke-crossed farmland of the Lincolnshire Fens. Joy Ellis launched the series with Crime on the Fens in 2010 and has continued it steadily since, building a large recurring cast around Nikki -- her team, her complicated personal life, and a set of recurring criminal threats to the Fens -- across fifteen novels.
The series is the origin point for Ellis's wider Fens-set crime universe: its Greenborough police force and setting are later shared with her DI Jackman & DS Evans series, which follows a different pairing of detectives within the same fictional force.
Fifteen, published from 2010 to 2024.
Both are set in the same fictional Fenland town of Greenborough and its police force, with occasional shared minor characters, but they follow different lead detectives and can be read independently.
