Jekyll has Miranda, played by Meera Syal, and Benjamin, played by Patterson Joseph. Benjamin is one of the main bad guys, until he fulfills this particular trope (http://tvtropes.org/pmwiki/pmwiki.php/Main/BlackDudeDiesFirst). Miranda is a lesbian private detective helping out the show's protagonist, and if the world was a fair place she and her partner would have gotten their own spin-off series.
