Just when it seems that Superintendent Robert Skinner and his crew have solved Edinburgh's grisly Royal Mile murders--whose victims have included, among others, rising advocate Michael Mortimer and his colleague and lover, Rachel Jameson--the bottom falls out of the case. First: The suspect, samurai industrialist Toshio Yobatu, has diplomatic immmunity, so all the evidence in the world (which Skinner has: It's not often you find a victim's testicles in the perp's dresser drawer) won't do any good. Second: Yobatu refuses to talk and, shortly after returning to Japan, hangs himself. Third: New evidence suggests that the solution was a masterly frame-up by diplomatic terrorists from still another corner of the globe whose stakes include...the legitimacy of Israel, the rise of militant Islam, and the fate of the free world. Wow. The procedural/international conspiracy mix is intriguing and spirited, though newcomer Jardine carries a lot more conviction as long as he keeps his distance from those Middle East death-dealers and the Foreign Office sharpies who are covering up for them.
