It comes at night. He watches you sleep. And waiting… Lincoln Rhyme and Amelia Sachs are back with another dark case.

When a woman realizes that someone forced the seemingly impregnable lock on her apartment door during the night and rearranged her personal belongings while she slept peacefully, she is horrified. This burglary, the police learn, sends a message to all of New York: here comes a new criminal who will stop at nothing...

Lincoln Rhyme and Amelia Sachs are assigned to the investigation. They quickly discover that a brilliant criminal dubbing himself "The Locksmith" is capable of defeating every lock and security system ever devised. However, as the list of his victims begins to grow, the police force discovers what appears to be a huge mistake in solving one of Rhyme's previous cases. A man is fired from his job as a consultant to the investigation department and faces a difficult choice: leave his current job or risk prison and solve the locksmith's mystery before he sets a final trap for someone...

While some of the big names on the American crime shelf show signs of fatigue or rush as they mass-produce more titles, Jeffery Deaver cannot be accused of lowering his standards. His dialogue and twists in "Night Watcher" are as sharp as ever.

"Night Watcher" is another superhit from this very prolific master who still retains the same enchanting magic for almost four decades! I love it and I'm always ready for more.
