It is one of those books. It is that few characters left.
There are parts of Scotland that are like parts of Carl Hiaasen's Florida. That was where Gavin Hutchinson grew up, and to whence he has returned after an express career that has taken him to the top of a world-wide hotel chain; where, on the coast nearby, Gavin is having a former oil rig converted into a giant hotel complex, the first of its kind, and to which he has invited his year to a re-union aboard the floating giant before it opens.
Unfortunately for Gavin's plans, scarcely has the party arrived than a gang of mercenaries (mostly recruited from the minimum wage end of the labour market, and already reduced in number due to some experiments with a rocket launcher) attempt to occupy the rig. Following S.O.P. they close down the hotel, but have not allowed for the wayward passions which have lain low in the breasts of ex-schoolboys and -girls for many years, but almost immediately after meeting again drive one or two (well, pairs really) to go upstairs and explore the facilities.
Soon afterwards comes an unhealthy conjoining of mercenary and masonry saw.
After that comes the more in-depth revelations of the human passions. Or, an insurance racket as some might call it. And a bit of double-crossing. And finally, that reversion to the World War Two meaning of "blockbuster".
A note at the beginning of the book says "The following is based on a true story". So who knows, I might be writing my own book in two months time. I've just got to hope that the evening goes like this book, with a bang.
