Berg's brother and sister each had different perspectives on their baseball playing brother, and each supported separate books about him. The sister's had limited printing, it took me a while to get a copy. Berg was a very interesting fellow. It isn't just baseball and spy... it's how he could walk in and out of places, drop in on people, disappear for periods of time. One tiny insight, he liked reading all of a newspaper; unread, he considered it "alive", and once he had read it, it was "dead". He didn't like folks messing with his newspapers.
