Killer Weed

Murders, Mystery & Marijuana

“Killer Weed hooked me on page one and I savored the references to San Francisco in the 1960s. A fascinating story with a strong ending.”
— Grace Slick, vocalist, Jefferson Airplane

“Castleman illuminates the hippie era vividly—and explains the derivation of ‘psychedelic’ and how the Grateful Dead and Jefferson Airplane got their names. His portrait of the business side of weed is detailed and authoritative. San Francisco—both then and now—comes alive. In addition, Killer Weed features sympathetic characters and a compelling, nuanced portrait of a marriage under duress.” — East Bay Express

“The San Francisco marijuana scene, from the glory days of Haight-Ashbury to the latest fight for legalization, forms the backdrop of Castleman’s entertaining fourth Ed Rosenberg mystery.” — Publisher’s Weekly

While running for mayor of San Francisco, a former pot dealer and author of best-selling guides to growing weed is assassinated. Former newspaperman, Ed Rosenberg is hired to find out what happened to a tech billionaire’s birth mother who was a small-time marijuana dealer shot to death in Golden Gate Park in an unsolved 1968 murder. His research about the Haight-Ashbury’s tie-dyed past illuminates that storied era and introduces him to a rogue’s gallery of aging hippies, who, he realizes, may have been involved in the candidate’s murder. Then someone starts shooting at him…

Killer Weed is a fast-paced, ingeniously plotted novel with characters so real you’ll want to turn on, tune in, and drop everything to reach the surprising, deeply satisfying conclusion.
