I had high expectations for The Siege of Krishnapur, perhaps too high.
JG Farrell's book is a fictionalised account of the 1857 Indian Mutiny and Siege of Lucknow. It's nearly all set in the British residency in Krishnapur, North India, and features a cast of characters of whom the Collector is perhaps the most important. He's obsessed with the 1851 Great Exhibition of the Works of Industry of All Nations that was staged in London. Other memorable characters include Lucy Hughes the "fallen woman", Harry and Fleury who both fall under her spell, and the two doctors, McNab and Dunstaple, who hold opposing views on the causes and treatment of cholera.
But it took an age for me to get into the story. It started well enough, explaining that the "first sign of trouble at Krishnapur came with a mysterious distribution of chapatis", which held a promise of the humour I'd heard is a great feature of the novel. Unfortunately the style of writing didn't appeal to me and I found my mind wandering. I'd read around three-quarters of the book before I really felt engaged.
As for the humour, it's more absurd than funny-ha-ha, although I did actually laugh out loud at two points, both during the siege itself: one relating to the misfiring of a gun, the other to the relative merits of Shakespeare and Keats.
I think it'll improve on a second reading.
