It's nearly been a full decade since British author Paula Hawkins made a name for herself in the literary world.

Crime thriller The Girl on the Train was a global number one bestseller - it sold over 23 million copies and helped solidify Hawkins' place in the crime fiction sphere. 

She's returned with her latest work, The Blue Hour, and fans and critics alike are calling it her best book yet.

Hawkins says her strategy to keep readers hooked is to keep little plot twists coming - and encourage readers to go back and look for hints.

"There are obviously lots of different ways of getting into books - and some are slow burns. But it's a great thing where you come up with an idea and think - oh yes, I can grab them with this one."
