Miss Jones, awakened by a terrible rumbling and nearly crushed by a falling armoire, finds herself in the midst of the Great San Francisco Earthquake. In the confusion and devastation of the ensuing fires, Fremont learns to drive an automobile, finds herself pursued by two ardent suitors, comes to have disturbingly romantic feelings toward her sleuthing cohort, the mysterious Michael Archer, becomes involved with murderous smugglers, and makes a discovery that almost costs her her life. How several murders relate to Fremont's discovery, how she escapes a terrible, watery death, and how she is reunited with a newly amorous Archer make Fire and Fog a more than worthy successor to Dianne Day's much-heralded debut.
