The kangraoo books really nail the comedy thriller thing very well. It seems like a fine line to tread, but it's done with such skill you hardly notice how hard it should be to weave those two ideas together. The narrative feels like a slow burning fuse, it builds and builds and you know there's an explosion coming, but there's just enough comedy to defuse the tension every little while so you don't suffer from tension fatigue. When the explosion at the end comes, it is fast and satisfying. This book kept me up late on more than one evening because I just needed to see what happened next.
