San Francisco in the 1970s was dominated by larger than life characters like Jim Jones of the Peoples' Temple, Patty Hearst the heiress turned terrorist, the Zodiac killer, Harvey Milk, George Moscone and Dan White. Author George Albert Brown evokes those heady times with equally colorful characters in "Who killed Jerusalem", in this whodunit with a literary homage to 18th Century English poet William Blake set against the backdrop of San Francisco.
