Do you trust the couple next door?
When Lena overhears a conversation between her next-door neighbours, she thinks she must have misheard.
After all, the Morgans are a kind, retired couple who have moved to a suburban street in Bristol where nothing ever happens.
But it sounded like they were planning a crime.
Her family and friends tell her she's made a mistake.
Yet the more Lena looks into the Morgans, the darker things seem.
And the more she fears it might be linked to a secret from her own past.
Because, if her suspicions are true, then someone is in real danger.
And it might just be her...
