The DCI Isaac Cook mystery series runs eighteen books from 2015 to 2024, making it a substantial run in the procedural genre. The first book, The Vane-Martin Conundrum / Murder Without Reason, establishes Isaac Cook as the detective at the center of the series, and the following books mostly carry “Murder” in their titles — Murder House, Murder in Little Venice, Murder in Notting Hill, Murder in Hyde Park — lending the series a recognizable identity across its middle run.
The later entries broaden the title choices: Six Years Too Late (2019), Grave Passion (2020), The Hero’s Fall and The Vicar’s Confession (both 2021), Guilty Until Proven Innocent (2023), and the final two books, Devil House and Deadly Secrets, both released in 2024. Reading in order from the first book is the best way to follow the development of Isaac Cook and the cases that define the series.
