I'm a big William Boyd fan and was not disappointed by his latest book 'Ordinary Thunderstands'. It was a classic thriller / murder conspiracy novel where the central character gets caught up in stuff he doesn't understand. However, what I particularly liked was the London setting. Most of the action takes place in modern day Chelsea and Rotherhithe and other sections around the river.
It's certainly not his best book (Any Human Heart is my favourite), but still really good. Recommended.
