I remember seeing a childrens program about a bunch of kids that solved some crime, I don't know whether it was just a one off or a series. I think it was Australian, and I know it had a deaf and dumb child who used to carry a dolly around with her. Any ides on what this might have been. Possibly early late 80's early 90's.
I asked the same question a couple of weeks ago. Did it have talking rucksacks in it, and set in a sort of community centre. I also want to know what it is called.
