Entry updated 15 September 2025. Tagged: Author.
(circa1970- ) UK author of the Kat and Lock sequence of Near-Future crime thrillers beginning with In the Blink of an Eye (2023). A partnering of police officer Kat Frank with a Computer-housed AI AIDE (Artificially Intelligent Detecting Entity) who goes by the name Lock enables the solving of crimes not decipherable without intuitionally acute number-crunching digital help. Lock, who presents in hologram format as a Black man, is literal-minded but may be able to learn how folk work. [JC]
