The third part of the series is so pleasant skuduggery quickly and stunningly written that reading pleasure not too lasts - because you can not put the book down. The story itself is devoted to the attempt of the "faceless" to invade the human world and the - to prevent chaotic attempts of the "skeleton detective," this - as in the past already. Whether he succeeds so, you can learn when you read the book. The story is very strong tailored to Valkyrie balance, which makes them for me the main character of the book. Of course all the old acquaintances (Tanith Low, China Sorrows, ...) of the party, which raises no boredom. In addition, some of the open issues in the first two volumes are compiled and completed. Finally, the book down is faster but also more brutal (the recommended age 9+ is set too low for my taste; 12+ would be more appropriate) and the circuit itself then acts as a stop from 100 to 0. For fans of the series a must, recommended for others, but the first two volumes should have read before.
