I've read a few Gerald Seymour books, enjoyed them all, but this one was slightly disappointing.
The Dealer and the Dead follows a familiar Seymour template: some deeply flawed central characters, a setting in one of recent history's hotspots (Vukovar, site of one of the fiercest battles in the Croatian War of Independence), a bit of inter-agency feuding and distrust, all told in cool, detached prose. In Seymour's best works - A Line in the Sand, Harry's Game, Holding the Zero - we grow over time to care about his morally ambivalent characters. But in The Dealer and the Dead the two central chacters, the hired killer and his target, both start off unlikeable and, if anything, grow more unsympathetic the longer the story goes.
The story dragged at times but the climax, though far-fetched, was rivetting.
