This is the sequel to "A Darker Place", which itself wasn't published that long ago. The jacket blurb/plot summary provided above is actually quite misleading. The Russians decide to assassinate most of the members of General Ferguson's team and all this action happens within the first 50 or so pages. The rest of the book is the story of how the attacks were planned, told in flashback. Within this flashback is another flashback which explains the life story of Daniel Holley, the ex-IRA arms runner (i.e. Dillon #2) who the Kremlin tasks with arranging the executions. Consequently, Dillon & co don't feature at all in the majority of the book and there is no Ferguson-led "hunt" for the perpetrators, the fate of all of whom we know by page 50. Anyone expecting the violent deaths of half the team followed by Dillon ruthlessly hunting down those responsible for the rest of the book (and I had hoped) will be disappointed.
Why Mr Higgins decided to structure the book this way is anyone's guess. By having the attacks first and then their background told in flashback, the author robs the book of any real tension and excitement - we know what the outcome of those attacks is (I won't reveal it, but have a guess...) so there is little drama in reading about how they were planned. Holley's back story is Higgins' standard "good guy witnesses something ghastly and so joins the IRA for revenge" template. He is essentially a new Sean Dillon and one wonders whether this book is designed to introduce him up for new adventures. I noted that this time the American president isn't named and there is a hint that Jake Cazelet has finally left office. Other details remain the same as before - everyone spends large amounts of time wearing Zeiss glasses and drinking champagne.
The attacks on Ferguson & co should have been tagged on to the end of "A Darker Place" and the rest of the story dispensed with; maybe that was the original intention before someone suggested spinning it out into a whole new book. I found myself skip-reading the last quarter of the book because it simply wasn't interesting. I kept hoping for a riverting twist in the tale - there is one of sorts, but like most of the denouements in the Sean Dillon series it is all over in the blink of eye and leaves you wondering why it is that all the good guys wear body armour and all the bad guys don't. It's been some years now since Hannah Bernstein was killed off - Jack Higgins really needs to take an axe to some other characters if he wants to keep the Dillon saga going, because as it stands now this series is completely out of steam and devoid of interest. That said, I'm sure I'll read the next one...
