The Serial Killer's Wife [Audiobook]

Beth and Tom Hardcastle are the envy of their neighbourhood - they have the perfect marriage, the perfect house, the perfect family.
When the police knock on their door one evening, Beth panics. Tom should be back from work by now - what if he's crashed his car? She fears the worst.
But the worst is beyond imagining.
As the interrogation begins, Beth will find herself questioning everything she believed about her husband.
They're saying he's a monster. And they're saying she knew.
