First episode with Don Barker as Det. Sgt. Harry White. The opening titles were changed slightly to include him in the sequence.
After George Mallaby's departure in the previous episode, there were reports that Norman Yemm was asked to return, but turned the offer down because he had accepted other commitments. Maurie Fields had also been considered as a replacement - he would have reprised the role of Det. Sgt. Arthur White that he played in The Friendly Fellow (1973), but he also had to turn the offer down because of his on-going role in Bellbird (1967).
