(Now, THAT'S Trivia #10) More Multi-Casting

This week, we're going to get away from questions about M*A*S*H, but not all that far away, as there is a connection to M*A*S*H in today's answer. Just like last week, this question concerns multiple actors playing one role, this time all during the run of a single TV series, and with, just like the case of the different Darrins on Bewitched, no acknowledgement of any change in the scripts. Anyway, the question is:

Q:Over the course of the run of CBS's Cagney and Lacey, how many women took on the role of Chris Cagney, and who were they?

The answer is, as the name implies, available at The Answer Blog.
