SYNOPSIS
In 1969 the British police are held to be the most trusted and effective force in the world, but all that is about to change. When a desperate south London villain tips off The Times about how he is being extorted for money by a detective in the Metropolitan Police, something much more shocking is discovered: that at the heart of the Metropolitan CID there exists a "firm in a firm", a secret network of corrupt coppers.
