Ellis Peters's historical detail is very accurate and very minute, and therefore is not only interesting to read but good for an actor to acquire a sense of the period. And the other thing I think is that an actor lives in the land of imagination.
I love a lot of the New York bands, but Patti Smith stands out. I just read 'Just Kids' and it's an inspirational, well-written account of an emerging New York artist in the late seventies.
