Fantastic read, which, again, led me to Nathanael West, particularly 'Day of The Locust', then his other works. Quick reads but engrossing.
'Hells Angels' is my favorite H.S.T. book. He was right there in with them.
Read some great true Hollywood crime books. 'City of Nets', 'L.A. Noir' and 'Tinsletown'. Mickey Cohen involved in one, they were particularly good.
