I heartily recommend the Secret Barrister's book "Stories of the Law and How It's Broken"

For anyone interested in UK law and in particular the parlous effect of successive cuts on our justice system, I can heartily recommend this book:

The Secret Barrister: Stories of the Law and How It's Broken

Here is an excerpt from the chapter which exposes the increasing number of false complaints:

But there will be cases where there is simply no other approach than to firmly and clearly put to a witness: you are lying.  And to make them relive every second of the events they describe so that you can clinically and decisively shred every sentence they deliver, building to a closing speech where you publicly implore a jury to reject the complainant as a liar.
