There's the usual Tintin fun to be had, but it feels like the set-up of a story, which of course it is, rather than an adventure in itself.

There are some nicely effective sections, the best being Tintin's dream-vision of the mummy, Rascar Capac. Or, was it a dream-vision? I'm looking forward to the next instalment, Prisoners of the Sun, which I hope will pay off on the set up of this book.
