Anna and Reid weren't meant to be. She's a fiery American journalist; he's a stoic British detective - it was nice while it lasted. Until it wasn't. And Anna is over it now anyway. She's on the scent of a career-making story - a suspicious death amongst the cloistered elite world of Cambridge University. But the more she investigates, the more there's only one person she wants to talk to about it. She starts writing Reid a long sprawling email - it's not like she's ever planning to send it. Until suddenly, her hunt for a killer leads her into desperate trouble. And the only detective she can trust with her life is the one who broke her heart.
