I was drawn to this by its top-rank cast and I was glad that I stayed with it. It sets out its stall in the first 15/20 minutes and it it is one of those 'who do you beleive' type of thrillers. It dips somewhat in the middle (the Kenneth More character is entirely superfluous) but once it reaches the court scenes the satisfactory tying-up of its diverse plot lines is excellent and example of how these things should be done.
