Insomnia — Robert Westbrook

Los Angeles detective Will Dormer has arrived in the wilds of a small Alaskan town to hunt down the killer of a teenage girl. Already on the edge, Dormer faces an unnerving twist in the case when a second murder occurs...and he's left holding the gun. The crime is now under investigation by local detective Ellie Burr, but when Dormer comes up with an unexpected alibi, he isn't even considered a suspect. The truth of what happened need never be revealed. He doesn't have to say a thing.

But Dormer has something else he never counted on. A witness. A killer who's going to make his life a waking nightmare.
