Kamen Artist

Built up nicely, had me guessing and wondering where it would turn next until about 2/3 of the way in. It was hard to get a grip on the main character for a while seemed shy and unassuming then is charging into bar fights and drinking himself senseless with prostitutes. Still I enjoyed it until the end where by I had figured out the killer and the motive although it seemed crude and the grand finale just seemed absurd.
