Under The Beetle's Cellar is the second in Mary Willis Walker's 3 book Molly Cates series. Like her debut stand-alone, Zero at the Bone and her first Cates mystery, The Red Scream, it derives much of its suspense from the time constraint - in Zero at the Bone, the heroine has only weeks to claim her father's promise of financial security before she loses everything to bankruptcy. In The Red Scream, journalist/author Molly Cates is faced with the possibility that a death row convict who is only days away from his execution may be innocent, which would compromise the case for his guilt made in Cates' true crime bestseller.
In Under the Beetle's Cellar, the stakes are higher. A bus driver and eleven children are kidnapped by a fringe religious cult and held in a buried school bus while the cult awaits the apocalypse. The chapters set in the bus, with the solitary post-war (VietNam) veteran attempting to keep the children alive, distracting them with anecdotes and an improvised fairy tale, are alternated with chapters detailing Molly's investigation into the cult leader's background, and her access to the hostage negotiation team.
Based on the 1976 Chowchilla kidnapping of school bus by three well-to-do men, the story plays out over weeks, rather than the 16 hours of the Chowchilla incident. Here, Walker's villain is a maniacal leader of a fringe Christian group, and despite the comparisons to Silence of the Lambs, the villain hasn't the originality and sophisticated menace of Hannibal Lecter - in fact, I found it a very implausible stereotype of religious mania. And the attempts to position Molly so that she is integral to the investigation and rescue attempts, never quite ring true.
Despite a plot that is more sensational (even to the point of being lurid) than The Red Scream, I found TRS more compelling because Molly remained center stage, and because of the unique moral dilemma she had to resolve. On the plus side, it is well paced, and much better crafted overall than many of the very recent novels I've read in this genre.
