Disappointing . I've read all of Iris Johansen's novels and thoroughly enjoyed many of them--this, however was not one of them. I found the plot hard to follow with too many references to her previous book. What mysterious event happened to Jock and Royd? Who is MacDuff--well if you haven't read the previous novel, you'll never know
NEG
