I finished this fourth book in the Ed Loy series a couple of days ago and as usual with Hughes' work, I enjoyed it a lot. I'm not going to say too much about the plot here, as really you should start at the beginning of Loy's story with The Wrong Kind of Blood. The series starts with Loy returning to Ireland after twenty years away, ostensibly to bury his mother. But his American Dream is in tatters too, and he's not going back right away--as I guess you can tell from the fact that this current work is set in Ireland too and he hasn't been back to the States in between.
I like the homage that Hughes pays the late Ross MacDonald's work in the Loy series. Ireland has a lot of family secrets to dig up and apparently no tradition of P.I.s with shovels until the advent of Loy. This fourth novel is a bit outside the usual pattern, although there's no need to panic--a ruined family or two lies at the heart of the tale. But All the Dead Voices takes on the consequences of the Troubles and there's more mention of paramilitary organizations than we're used to dealing with in Hughes' works. Actually, a good companion novel from north of the border would be Stuart Neville's recent Collusion.
Personally, I missed seeing more of Loy's old friend Tommy Owens in this book, as he always provides a bit of comic relief, albeit usually of a criminal kind. He's there, though, for a few crucial plot points. And that'll have to do.
