John Halliday
Back in the 1990s, Halliday was a CPS officer working out of the same police station as Brightman.
The pair collaborated on a number of dodgy convictions, acting outside the law to entrap criminals. Halliday has now worked his way up to become the second-in-command at the CPS, and is keeping an eye on Maya from the inside.
