'I'm sorry, Sam's not available, ' says the woman who answers my husband's phone. I can't place her voice, so I politely ask who she is. Her answer sends my world spinning out of control: 'I'm his wife.'

I know I want to marry Sam the moment I meet him. After I lost my beloved mother so suddenly, this charming, softly spoken architect with his deep-brown eyes is just the fresh start I've been searching for.

I'm delighted to be expecting our first child before we've even had a chance to plan a honeymoon. I want our family to work so I try to ignore his long work trips. I turn a blind eye to the private calls he takes and I listen to his excuses about why the money keeps disappearing from my bank account. After all, he has no idea what I've been doing in our house whilst he's away or how I really made that money.

Then I find out Sam's got more to hide than I ever imagined was possible. Because my husband is leading a double life. He's already married to someone else.

But what Sam doesn't know is that he's not the only person keeping secrets.

And he has no idea how far I'll go to protect myself...

A totally unputdownable, twisty, will-leave-you-gasping story of marriage, guilt and lies. If you love Lisa Jewell, Gillian Flynn and Paula Hawkins, you will not be able to sleep until you've finished every last page of The Bigamist.
