Two dead women. Two identical neckties. Zero clues.

When a woman is found strangled in her own bed, the spotless crime scene suggests a killer who planned every move. But Detective Madison Knight spots a photograph on the nightstand—one detail that tells her this murder wasn’t random.

Before Madison can determine what it means, a second victim is found strangled with the exact same brand of tie. Madison realizes she isn't looking for a disgruntled lover—she is chasing a cold, calculating serial killer who leaves nothing to chance.

As the clues begin to click together, Madison uncovers the killer's pattern. If she's right, the killer is already hunting his next victim... and Madison is running out of time to stop him before he strikes again.
