Overview

The heroine had little time for romancing newspaper reporter Walter Jameson, what with Doctor X, alias Marcus Del Mar, threatening American democracy in general and master detective Craig Kennedy's designs for a new torpedo in particular. Whenever Doctor X has Elaine or Jameson in his grasp, they are inevitably saved in the nick of time by a mystery figure garbed in black.
