[7] Walton began her career writing romance novels using the pen name Maxine Barry.
They are set in Oxfordshire, with the lead character being CID DI Hillary Greene,[4][11] who works out of Thames Valley Police headquarters in Kidlington and lives on a narrowboat.
Whereas Inspector Morse spent his time solving the surprisingly[clarification needed] large number of murder cases in the city of Oxford, DI Hillary Greene works in the towns and villages in the north of Oxfordshire, where there are also a large number of such cases.
Subsequently, Joffe Books republished the Hillary Greene "Narrow" series under new titles, which almost all contain the word 'murder'.
[1] Set in the city of Oxford, this series features Probationary WPC Trudy Loveday and coroner Clement Ryder.
