Line of Vision - David Ellis

David Ellis's Line of Vision won the 2002 Edgar Allan Poe Award for Best First Novel by an American Author
Marty Kalish is a young man suffocating in the heat of an affair with a married woman named Rachel. When Rachel's husband disappears one night, Marty is one of the first to be questioned. With few likely suspects, the police arrest him for murder. We know Marty was outside their home that night. We know he has a motive. We know he's guilty of something. But is it murder?
Everything we have learned—about Marty as a man, his affair with Rachel, and the night in question—comes from Marty himself. But as the trial unfolds to a jaw-dropping conclusion, we learn that there is more to the truth than one man's narrow line of vision.
