One of the advantages of doing a show for nineteen years is an ever-growing roster of memorable returning characters. Every so often viewers get to enjoy people like Terrence Meyers, James Pendrick, Louise Cherry, and the entire Newsome clan, and the worlds they inhabit. Not all of them may be particularly likeable, but they’re certainly remarkable and always hilarious, and they play just as big a part in Murdoch Mysteries’ ongoing success as the main cast does.
