Senior crime reporter Cindy Thomas is writing a biography of Evan Burke, a notorious serial killer who sits in solitary confinement in San Quentin. She’s kidnapped by thugs wanting her to talk about her best friend, Lindsay Boxer, who’s an SFPD homicide detective and the story’s main character. San Francisco has a restrictive new gun law, and gun-totin’ folks everywhere have their boxer shorts in a twist. A national resistance movement has formed—Defenders of the Second—whose motto is “We will not comply.” They find it outrageous that the new law makes it illegal to own a gun that can kill 50 people with a single clip. Meanwhile, lots of bodies show up: A young girl disappears and is later found dead in a ditch, and ex-cops are found dead with their lips stapled shut and “You talk, you die” written on their foreheads. An inmate is found hanged in prison. And “a massive but unspecified load of military-style weaponry was en route from Mexico to the City by the Bay.” In a “frustrating, multipronged case,” there’s a harrowing shootout memorialized in a video showing “twenty-two of the scariest seconds” of Boxer’s life. She’s an appealing series hero with loving family and friends, but she may arrive at a crossroads where she has “to choose between my work and [my] baby girl.” The formulaic story has unmemorable writing, but it’s entertaining and well told. You probably won’t have to worry about the main characters, who have thus far survived 21 adventures. Except for the little girl, you can expect people to get what they deserve. It’s relatively mild as crime novels go, but the women characters are serious, strong, and admirable.
