Christmas Icons in Mystery Shows: Due South

Strolling reindeer in the background.

A number of mystery shows have included a Santa Clause or Santa Clauses as suspects: Diagnosis Murder, Bones, and Due South are a few. 

Due South stands out because it is full of Christmas icons that simply happen--there and gone. 

For instance, at one point, Constable Fraser sees a reindeer in the police station. It could be the reindeer that a prior Santa says he lost but no one else seems to notice, so it could be a hint of what is to come: 

Fraser's dead father, played by the marvelous Gordon Pinsent, shows up to give him advice...and remind him of the bond between fathers and sons.
