Stevie Gordon is lonely and obsessed with her ex-boyfriend, James Cowley, stalking him even though he’s married. But when James’s latest mistress is found murdered, gruesomely posed in the bluebells of Thamespark, Stevie is shocked — and terrified.
 
She struggles with her own memory: she has frequent blackouts due to heavy drinking, and her troubled childhood has left her unsure of what’s real.
 
Detective Inspector Sebastian Locke and his Thamespark squad take on the case, uncovering links to a previous victim. But the deeper the investigation goes, the more it seems that Stevie’s mind might be betraying her — or someone else is manipulating events from the shadows.
 
With every twist, it’s unclear: is Stevie capable of murder — or is she just the next target?
