H. G. Wells chases Jack the Ripper through time, via his infamous time machine, to current day San Francisco, Jack just happen to be a sociopath friend of dear H.G.'s. San Fran is a great back drop to the novel, and their battles. H.G. even finds love. This book went on to make a great film by the same title. In fact H. G. and Mary married in real life, McDowell still considers Mary Steenburgen his greatest love, though they divorced and remarried years ago, It is also his favorite film.
