Jack Higgins may not be running out of his fascination with modern weapons, fine dining, glamorous women or the IRA but he appears to be slipping on plot and character development. Sean Dillon makes Doc Savage and Dirk Pitt look like pikers. And this curious extension of gentlemanly methods for attempting to kill one another -- sending a crazed assassin and then both sides meeting later at the Savoy to exchange notes -- strains credulity.Higgins has done some first-rate work. Had this been published twenty-five years ago, this might have made a difference. It wasn't and it doesn't.
Negative

Classic TV special, but the promise of a "digital copy" is misleading. On the back of the cardboard slipcover, in tiny print, is listed this limitation: "Windows Media-compatible only." It is implausible that a consumer would come across this disclaimer when making a purchase decision based in part on the overtly advertised inclusion of a "digital copy," a term most consumers associate with the ability to view media on an iPod.
