I too found Boiling a Frog a bit below par for Christopher Brookmyre, who has quickly established himself as one of my favourite authors. He does this genre with panache and wit and not too much violence. I didn't find this one as good as 'One fine day' for example, but was a pretty good read nonetheless. I had some problems at the end with visualisation of all the goings on, but that didn't really reduce my interest or enjoyment. A good book, and (surely coincidentally) very topical.
