Kirsten and Nick are enjoying a weekend away until, on their drive home, they accidentally run over and kill a man. They should call for help – but they have too much to lose, and no one can know the real reason they’re here. Instead, they make a split-second decision to conceal the accident.

Amy and Greg have just celebrated their tenth wedding anniversary. Amy is expecting a baby, and they couldn’t be happier. So when Greg fails to come home from a dog walk one weekend, Amy knows the police are wrong to believe he left of his own accord. Someone must be behind Greg’s disappearance, and Amy won’t give up until she gets justice – or revenge.

‘Dark, gripping and suspenseful. This smart page-turner had me racing to the totally unexpected end!’ Lesley Kara

‘Revenge is a dish best served ice cold in this tense, twisty and unpredictable thriller.’ T.M. Logan

Diane Jeffrey recently spent some time with The Big Thrill discussing her latest thriller, THE OTHER COUPLE.

Can you pinpoint a moment or incident that sparked the idea for this book?
I knew that I wanted to write a novel about a character who resorted to revenge when getting justice was not an option. I wanted to write a cat-and-mouse story between two women, who end up with more in common than they would like to admit.

A novel is such a major undertaking; there’s the writing of it, of course, then you’re spending months and months revising, polishing, and then promoting it. How did you know this was the book you wanted to spend the next couple of years on?
It took me one year to write. I absolutely loved writing it because I loved the characters I created and wanted to spend time with them.

I’ve just abandoned the work I was doing on my seventh novel, after four months, although I don’t think there’s anything fundamentally wrong with it, but I was finding it a chore. Usually, writing is both a pleasure and a necessity, and I wasn’t in love with my manuscript. I may go back to it one day, but I want to write something else first – something that I enjoy writing.

In addition to a great read, what do you hope readers will take away from this story?
I hope my readers will remember the characters when they’ve finished this book. I also hope they might look up my backlist!

What can you share about what you’re working on next?
I’m about to start work on my seventh psychological thriller. It will also be set in England and will have two time frames.
