Review by malcolmgsw

Even by the standards of Merton Park this is a very routine thriller.Dermot Walsh is an undercover policeman who worms his way into a diamond smuggling gang by falsifying a prison record.Sydney Tafler,as usual plays on the wrong side of the law is caught by the police and manages to escape by asking for a glass of water.It is quite laughable.The finale such as it is mainly takes place in the dark,so you don't actually know what has happened till someone turns on the light switch.The problem is that plot is so routine that you just give up the ghost long before the end credits roll.Such a surprise when someone as experienced is the director.
