I enjoyed his three earlier Cale books, in descending order of pleasure from the first one. All three were gripping, exciting stuff, as well as developing the fascinating, and irritating, character of Thomas Cale and a few others. But this was a sequel too far. The beginning was quite promising, with an alternative version of the assassination of the US president, and gripping in places, and the end wasn't too bad. But the middle - the long, slow, discursive, pedestrian, details of Cale's tedious life at Malfi in the shadow of his past loves and life stretched over hundreds of pages - was extremely boring. I struggled to get through it, and the references to characters and incidents in earlier books don't help. After the end of this bloated, boring novel - albeit with some witty bits and mildly entertaining touches - there's an excellent essay by the author about fact, fiction, modern life and history, and the importance of story-telling. Very well done, but serving to highlight the main weakness of the preceding story - it just wasn't very entertaining.
