Unknown title

Plot: Businessman threatened by a gang, one of whose members is working as his chauffeur and driving around his daughter.
 

	What a sweet little child. In Prisoner she had a piercing scream that, sadly, she couldn't hear herself. A real life Crawford Production... Who was she in Prisoner?
	Secretary to the businessman, motherly and caring. But whose niece was she in Prisoner?
	In the foreground, a non-speaking appearance by an actor who played the husband of one of the officers. Unlike Dame Edna, she never sang "I miss my Norm"?
	No, it isn't Mrs Hudson there in the middle. Could it be Prisoner's least likely cat burglar?

I didn't see the credits on the Kabel 1 website, but these are the guest appearances I think I spotted:

Anna Crawford (who is the real life daughter of executive producer of the series) as the little girl Emily Grayson
Yoni Prior as the boss's secretary
Bill Johnston (one of the men round the boardroom table)
Billie Hammerberg as the housekeeper

and (not pictured above)
Penelope Shelton as Emily's school teacher
