Characters:
     John Cardinal - played by Billy Campbell
     Catherine Cardinal
     Lise DeLorme - Cardinal's new partner
   
My comments:  Season 2 ended where John Cardinal's wife, Catherine, who was bipolar, has just jumped off a big building and killed herself.  Good mystery.  Good chemistry between Cardinal and his partner, Delorme.
Season 3 was slow and depressing.  I'm glad there are only six episodes.  There are two mysteries unfolding, one of a vigilante woman who has taken in three you adults and brainwashed them into thinking they are helping her create a better world.  And the other is John Cardinal convinced that his wife did not commit suicide in the last episode of season two, and goes on to prove it against everyone else's advice.  Even though it was depressing, it was interesting to watch.

Season 4 was good, but so dark, grey, and SNOWY!  Actually, the killer was killing by freezing his victims' loved ones to death outside in below zero temps.  Gruesome.  All six episodes were in blizzard-like conditions, frigid winter scenes.  The ending had Cardinal staying in Algonquin Bay and Lise heading back to Toronto to take a job there....but before leaving they started a relationship, so you're left knowing that anything could happen between them in the future.

     All four seasons have been pretty dark and depressing, both in story and setting.  I still enjoyed them, though.
