Herbert Asbury, author of The Gangs of New York and The Gangs of Chicago, turns his attention to chronicle the seedy underworld of San Francisco, from its gold-rush glories to its subterranean opium dens. Houses of ill repute play host to shanghaied sailors, and the Chinese tong wars rage around the city. San Francisco's historic past is here brought to life in all its scintillating and infamous glory.
