In this revisionist version of the Dodgers' exodus from Brooklyn to Los Angeles, viewed by many as a journey from Eden to Sodom, the Prime Mover emerges as less like Satan and more like Moses?visionary, flawed and ultimately justified.

He sometimes has difficulty with balance, offering only a few swift sentences on Roy Campanella's career-ending accident, for example. Readers may also wish for more about O'Malley's private life. We see the franchise owner as a consummate politician, a true mover-and-sh...
