«Matthew Frank writes so well and in DC Joe Stark he has developed a complex hero, remote yet relatable, decent yet conflicted. Equally compelling is Stark's nemesis, the sinuous Julian Sinclair with his reptilian charm. Tense and twisty, with a rich cast of characters, The Killer Inside is completely gripping. I ignored children, a ringing phone, hunger, everything just to devour the last hundred pages.»

Karen Perry, bestselling author of Your Closest Friend, -

«Detective Sergeant Fran Millhaven is just one of the best women copper characters you'll ever meet between the covers of a book . . . but Stark is the heart of this narrative. I am so looking forward to meeting him again . . . the moment Stark crosses over from soldier to CID detective is beautiful to behold. The action scenes, too, are terrific. Riveting»
