" Dirk Pitt novels are a guilty pleasure, so books about Isaac Bell, the turn-of-the-century detective are not quite what I seek in Cussler's books. The writing is good, but the situations and character's actions are not always believable (though the Pitt books are arguably as unbelievable) , and I found a few tedious passages where the author was simply showing off his knowledge of aeroplanes and aeroplane racing from the distant past. (The same is true of the train books he has written in the same series). The characters are not as well developed in this book as previous ones in the series. We see very little of Bell's fiancee, and Bell's co-workers add little to the plot this time round. There's lots of derring-do for those who like action, though. "
