The Adventures on Trains series excels at Agatha Christie style mysteries for kids. Sabotage on the Solar Express shakes this up a bit by taking pretty overt inspiration from the action movie Speed, and it really, really works.

The book gripped me from the very beginning and I sped through it. It was, tense, gripping and exciting, with once again great characters and lots of supporting illustrations. I do think that the story was missing a bit of logic - the actions of the villain of the piece don't quite make sense - but I didn't really care as I was having so much fun. 

It's easily the best in the series, even better than Kidnap on the California Comet which was previously my favourite. I loved it.
