I must say I'm always a bit of a sucker for the modern-day detective-novel trope of the multi-generational case, where incidents in the past affect the crime or crimes of the current day. Just as well, because it's rare to find a detective novel these days that doesn't have a "historical" element. What I find (wryly) amusing is that "history" is more and more often within my own lifetime. In this case, the Revolution of the title is the 60s revolution, political and sexual, and the key to one murder and one attempted murder in the present day is both sexual and political shenanigans at a 60s university, juxtaposed with the highly respectable life of a certain Lady Veronica Chalmers, one of whose young relatives is about to become politically very important.
If you see the words "politically very important", then of course you will understand that even though Banks solves the mystery, and we are kindly let in on the secret, there is a shadowy senior figure who makes sure the solution gets no further publicity and the case goes "unsolved". I thought Robinson cheated a bit on the ending - I was not in the least convinced that the murderous person who apparently committed suicide was in the slightest suicidal, but on the other hand, there was no indication that the shadowy figure was responsible for a cover-up. And believe me, I looked back and re-read, because I'm not used to saying, "well that's implausible..." as I finish up a Banks novel.
Nonetheless, I thoroughly enjoyed following Banks through all the twists and turns of his detecting, including the red herrings, mostly because as usual Robinson's characterizations are marvellous. I get only vaguely peeved when the whiff of male entitlement enters into Banks' relationships with his female fellow-officers or the latest lust object; meh, it doesn't bother me much. I'm happy to objectify Banks and his brain-power, so he can go ahead and objectify pretty young things if he likes. I'd prefer it if his much more substantial female co-workers (and, incidentally, subordinates) didn't have scenes where they seemed to be spatting over getting his attention and approval, though.
Four stars, because none of the basic virtues of the Banks novels are missing, despite my reservations.
