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.
