A reader review called Undisruptable 'the most cracking read since Shirley Conran banged out Lace in the 80s.’

It was made into a 1984 TV mini-series, and its trademark dialogue line was rated one of the best lines in TV history. Delivered by actor Phoebe Cates, its power is magnified by the huge silence she left mid-sentence.

We look at that, and the other ways silence can be a powerful communication tool: in speeches, sales negotiations, talking to staff, and sorts of other areas.
