He is a millionaire and she is a retired journalist, a perfect marriage where what abounds is love, and both are fans of unraveling crimes and mysteries. Many times they come across a strange event by chance and do not stop until they find out its origin. I think Robert Wagner and Stefanie Powers were at their best when they made this series, she was a beautiful and modern forty-something, and he had his second hit after It Takes a Thief. Watching it after 40 years, the show may have aged and be a little slow compared to what it is now and even its stories are somewhat repetitive, but in the 80s it was an original, intelligent series without explicit violence, the chemistry between Wagner and Powers was extraordinary, anyone would have believed it was a real marriage.
