Lockhart & Green Book 1
‘A gripping crime thriller’ Peter James
‘Intelligent crime writing… alarmingly plausible’ Frank Tallis
Ex-soldier Dan Lockhart has left the army and become a murder investigator in London’s Met Police. He’s also trying to come to terms with his wife’s disappearance… though he’s the only one who believes she’s still alive.
American Clinical Psychologist Dr Lexi Green has spent her life wandering and has nowhere she can truly call home. Having moved to London, she now treats Post-Traumatic Stress Disorder at a mental health clinic. But has she dealt with the tragedies of her own past?
Lockhart becomes Green’s patient when he enrols in therapy for his traumatic experiences. But, when he catches a psychologically complex murder case he can’t solve, he soon needs her expertise for a different kind of help - finding a killer.
