YMMV / Murdoch Mysteries S 8 E 1 On The Waterfront Part 1

• Complete Monster:
  • Cecily McKinnon is the seemingly benign Toronto harbormaster, but is later revealed to be the equally vile O'Shea brothers' cold and ruthless employer, profiting from the violence and fear they enact on the docks. Having Inspector Brackenreid attacked by the O'Sheas, McKinnon turns up to watch the beating for her own amusement and leaves the Inspector to die for investigating her criminal activities. When fellow businessperson Richard Dawkins uncovers McKinnon's Human Trafficking business, McKinnon has him brutally murdered and tries to frame Dawkins for her own crimes, nearly succeeding in avoiding justice and selling off several innocent women into slavery. When Brackenreid fights back against the O'Sheas, McKinnon murders the brothers to try and frame Brackenreid, and when confronted herself, she proves to be utterly shameless about her atrocities, making a final attempt to murder Brackenreid before being finally being brought to justice.
  • Mick and Tim O'Shea, who debuted in "The Death of Dr. Ogden", are a pair of psychopathic Irish immigrants who control the Toronto waterfront for McKinnon. The O'Sheas control the docks through violence and extortion, keeping people too afraid to challenge them, smugly reveling in their power over others. When Inspector Brackenreid investigates the O'Sheas' crimes, the brothers savagely beat him and leave him for dead, later threatening the Inspector's family to force his silence. They are revealed to be involved in Human Trafficking as well, selling women from Hungary into slavery. When businessman Richard Dawkins discovers the human trafficking and tries to save some of the women, the O'Sheas drown one of the women who managed to escape before brutally beating Dawkins to death. When Detective Murdoch tries to arrest the O'Sheas, the brothers sic their gang on the police, staying out of the fray until they have a chance to try and beat Murdoch to death.
