I had to order this from Australia, but I'm glad I did.

Brock has retired, but is asked by a defence lawyer to look into an aspect of her client's defence. This causes him to believe the client may be innocent. It is Kathy who has led the investigation resulting in the client being charged.

I thought this was excellent and am glad the door seems to have been left open fr further instalments. I'm not entirely convinced by the John/Kathy relationship, but that's a minor niggle.
