Query: Potentially five stars

A potential five star mystery spoilt by the lingering feeling that there will be a vocabulary test on the last few pages.This is the first Elizabeth George I've read and it's a really very good storey. Great plot, great intrigue, great mystery, great finish and well researched. However I'm not a great believer in entertaining novels like this being the place for an author to hugely demonstrate ones superior grasp of vocabulary.Maybe the words used are common in Jolly Olde England but a more International approach to vocabulary would make this a less grating experience.That said, it was still good enough for me to try one more.
