I finished the book - only because I was stuck on a plane with little else to do.
This must rank as one of the worst books I have ever read - despite Ben Elton's obvious talent.
The plot is silly, the action is just not credible, the characters were one dimensional and the style was irritating.
I enjoyed "First Casualty". In that book, perhaps Mr Elton moved away from the superficial to something serious, and was successful there.
"Gridlock" must have been bought by a publisher as they knew that the Author's name would sell copies, whatever the quality. If he'd submitted this anonymously, it would certainly have ended up, quite correctly, in the bin.
