Steve Wheeler is enjoying retired life in the New Forest. He does the odd bit of investigation work, but he likes his familiar habits and routines: the pub quiz, his favourite bench, his cat waiting for him when he gets home. His days of adventure are over: adrenaline is daughter-in-law Amy’s business now.

Amy Wheeler thinks adrenaline is good for the soul: she doesn’t stay still long enough for a habit or routine. She’s currently on a private island keeping world-famous author Rosie D’Antonio alive. Which was meant to be an easy job...

Then a dead body, a bag of money, and a killer with their sights on Amy mean an end to Steve’s quiet life. As an iconic new detective duo is born, a breakneck race around the world begins. But can they stay one step ahead of a deadly enemy?
