I enjoyed this - I haven't read any of the others, but picked this one up for its Welsh interest. It's a legal/courtroom drama (there are a lot of lawyers, and although one apparently gives his name to the series I wouldn't say he was the central character). The events mainly take place in 1969/1970 with some back story during the 1960s, and while it is a bit overtly didactic in places it would give anyone who didn't know the background a fairly good picture of Welsh nationalism in the 1960s, given inspiration by the failure to prevent the flooding of Capel Celyn, the peaceful protests about linguistic rights and the events surrounding the investiture of Prince Charles as Prince of Wales at Caernarfon. There's also a look at the more violent, minority fringe groups, and the distinction is made fairly clear. There are two elements to this story which may have been inspired by later events too - one is too much of a spoiler to give away, the other (choosing my words carefully here) reflects words allegedly said by a policeman to a suspect in a different Welsh case. The case involves a (fictional) bomb plot, so of course we know from the start that it was not successful. On the whole, a pretty accurate picture, although I am sure the IRA man would not have referred to "the Queen"!
