Emperor Norton's Ghost (A Fremont Jones Mystery)
Like all good historical mysteries, Dianne Day's books about a feisty  young woman from Boston named Fremont Jones who winds up solving crimes in and around San Francisco in the early 1900s are a delicate balance of odd and exotic period details and characters with motivations we can sympathize with today. The notion that Fremont's lover-partner, a Russian named Michael Kossoff, might be involved in a plot to murder the mad monk Rasputin is made more believable by his endearing habit of bringing home fresh pastries for breakfast. That Fremont's new friend Frances McFadden seems to have summoned up at a seance the spirit of that infamous 19th-century  San Francisco character who crowned himself Emperor Norton I of the United States and Defender of Mexico is balanced by the bruises Fremont notices on the battered wife's arms. And descriptions of a determined San Francisco rebuilding itself after the 1905 earthquake remind us of more recent Bay Area disasters. Day writes with wit and energy, and her Fremont Jones is a totally plausible modern woman born a few decades before her time but making the most of that accident of history. The first three books in this laudable series areThe Strange Files of Fremont Jones,Fire and Fog, andThe Bohemian Murders.--Dick Adler
