Joy Ellis writes British police procedurals set largely in the Lincolnshire Fens, using the flat rural landscape, isolated roads and waterways as part of the investigations. Her DI Nikki Galena series begins with Crime on the Fens and follows a hard-edged detective working with DS Joseph Easter on murders, disappearances and organised crime. A second long-running sequence pairs DI Rowan Jackman with DS Marie Evans, beginning with The Murderer's Son, while the Matt Ballard books follow an older detective facing cases with links to his own past. Ellis writes quickly paced mysteries with recurring teams, personal subplots and straightforward investigative structure rather than elaborate literary experimentation. Readers who like continuing police teams and regional settings will find the Nikki Galena and Jackman & Evans series the main routes into Ellis's large catalogue. Read more Less
