In "Killer Weed," author Michael Castleman writes the fourth in his Ed Rosenbery mystery series in which a Silicon Valley billionaire hires Ed to research the hippie era centered in the Haight-Ashbury district in San Francisco, while a popular mayoral candidate and ex-hippie drug dealer is assassinated present-day as Ed's wife is serving on the campaign. This discussion with the author took place on a 2013 episode of "Conversations On The Coast with Jim Foster" originating in San Francisco, California.
