Murphy's Law S02 E02 Bent Moon on the Rise

"A maverick Irish cop takes on the LONDON Crime World"

Murphy is assigned to a drug squad headed by Nic Winters after one of Winters' team, Aaron Parmer, commits suicide. There is a concern that race may have played a part. Soon after joining, Murphy concludes that racism isn't the problem: he suspects Winters of skimming some of the seized drugs. It becomes apparent that the entire squad is on the take and when a second DC is killed, Murphy begins to wonder to what extent Parmer's death was genuinely suicide.
