This is another enjoyable Sean Dillon (and Company) caper, the 21st featuring the former Provisional IRA enforcer, turned agent for the British Secret Service. While not my favorite in this long-lasting franchise, it carries most all of the hallmarks that have come to be known throughout. The main difference being, in the last several books, that Dillon, who is now about 62, is not as spry as he was when the series started, though he is still feared and a threat to most. The plot is fairly typical with Dillon and his cohorts (Brig Gen Ferguson, Capt Sarah Gideon, Maj Charles Roper, Billy, and his uncle Harry, Salter) having to "save the day," so to speak, this time from the plans of an Al-Queda man, known only as the Master who is unknown outside the circle of his Council and who has utter control over several assets worldwide. The identity of the Master does add a twist to the story. They are joined in their escapade by none other than former US President Jake Cazalet (who first appeared in the series in the 1997 book "The President's Daughter"). I will admit it is not one of Higgins' best works, with incorrect details such as a non-existent protection detail for an ex-president, but for a Sean Dillon fan, it was an enjoyable read, containing plenty of action with some twists and turns along the way. The main action takes place in Nantucket (Massachusetts, USA), Drumgoole (Ireland), Paris (France) and London (England), with a few other locations thrown in for good measure. I rate this book half way between a 3 (due to a few detail inaccuracies, though many popular authors suffer from this) and a 4 (as I like the characters and the plot with sub-plots), so will round it up. For those interested, the Sean Dillon tales begin with "Eye of the Storm" (1992).
