During this show 3 pairs of detectives - one after the other - makes life very insecure for many criminals in Palm Beach. The show originally aired on CBS as part of their late night after prime time viewing with a few other shows. I believe that was for all of season 1 and 2 then was picked up by USA. There were 3 sets of stars through out the series, but the first 4 to 5 years was story of Rita and Chris. Then there was the bad recasting for a season or less. Then we got Cassie and Tom. There were two very stable sets of the partners.
