Some love for the always fine Henry Darrow, as Harry's first police ally Manny Quinlan, is also in order; but I agree the chemistry between Zerbe and Janssen was terrific. I rank this as one of the three in my personal Holy Triumvirate of seventies detective series, up there with Columbo and The Rockford Files; this series was another excellent example of a stereotypical and hackneyed television genre being given new life through good writing and even better performances.
