Watching the Canadian TV series Coroner reminded me of the even better series Cardinal.
Excellent.
Season 3 was my favourite.
The suspicious death of Cardinal’s wife Catherine coincides with a double murder, and Delorme is ordered to take the lead in the murder investigation.
Reluctant to believe that Catherine committed suicide, Cardinal begins investigating other possibilities, whilst dealing with a succession of anonymous letters blaming him for the event.
Noelle Dyson, recovering from the death of her sister, tries to reason with another prospective suicide and is devastated when she fails to prevent him killing himself.

Season 4 was not as good, in my opinion. Still good, but not as good.
And there will be no season 5.
There have been rumours of a spin-off for Cardinal’s detective partner, Lise Delorme.
