The Collector (2004) - 1x05 - The Photographer

When Morgan Pym finds Stuart Peterson, he is a broken man, so sunk in despair that he welcomes the end of his days on earth. Following the murder of his wife, Peterson made a deal to take extraordinary crime photos, but has failed in his goal of changing society, instead descending into a private Hell of always being on the scene for the misery of others. Following the trail of clues in Peterson's pictures, Morgan finds that the Devil has taken an unusual interest in this particular client.
