Though Luis and Sheridan are happily in love, Sheridan's father, Alistair, disapproves of their relationship; Alistair fears that Luis will use his position as Sheridan's husband to uncover some of his nefarious business dealings and forbids Sheridan from seeing Luis. Luis and Sheridan defy him, however, and Alistair hires an actor, whom he fits with a mask of Luis's face, to trick Sheridan into believing that Luis is using her only for her money. The pair eventually catch the double but are unable to prove whether Alistair or Sheridan's brother, Julian, had been behind the plot.
