Tom Sharpe is definitely an acquired taste, and not all of his humour has necessarily aged well, but if you enjoy comedy in the style of Monty Python's Flying Circus, Fawlty Towers, with a dash or two of Benny Hill, then you might like this.
On the whole this was an alright read with a few humorous parts, but I got the sense that Mr. Sharpe painted himself into a corner towards the end, as the plot resolution seemed quite rushed and forced, compared to the rest of the novel. There are plenty of catastrophes, misunderstandings, plus some commentary about international relations in the late 20th century, but not to the same level of wit that Mr. Sharpe used when he satirised South Africa under apartheid in Riotous Assembly.
Worth a read if you like Tom Sharpe, but definitely not his best work in my view, and this is definitely a work of its time - it was published in 1982. I likely won't re-read this.
