Beneath the Twist: Lindsay Kent, author of My Twin the Murderer, on the challenges of writing a thriller with an emotional core . . . To me, every great thriller shares one essential trait: beneath the twists, revelations, and pulse-quickening suspense, there is something deeply human at stake. The stories that linger aren't memorable simply because of what happened, but because of why it mattered. Beneath the danger lies grief, love, betrayal, longing.
