Legal / courtroom thrillers recommendations?

[FawnDrench]

I really enjoy the trial and courtroom bits rather than over-involved background about the lawyers - I know there needs to be some of this of course.
Can anyone suggest anything gripping and with a vaguely credible development and outcome or ending or whatever.
Not John Grisham or Michael Connelly but sort of along those lines please.

Thanks a lot.

Simon Michael’s Charles Holborne series is great. The author was a barrister so very authentic

The Cut Throat Trial by The Secret Barrister - exactly as you describe and brilliant.
