They say write about what you know. In Ted Bell's case this would seem to be "not a lot", well, not about the UK at any rate. Bell's characters Hawke and Ambrose are straight copies of Dirk Pitt, and Sherlock Holmes only two-dimensional and without anything unique. Even the names he gives his charactors are cheesy. The back-story of a previous book, involving the murder of Hawkes new bride on the church steps, in Lorna Donne style, is brought up too many times without having any purpose in the current story, and Bell's knowledge of the UK seems to have been lifted straight out of the roaring twenties, and deserves to remain there.
What is also apparent, particularly in respect of the UK, is the lack of research Bell has done. Examples include placing the Grimpen Mire "The Hound of the Baskervilles" in northern England, not on Dartmoor in the Southwest, and referring to it as the Grimpen Moor, and not Mire.
Perhaps the most worrying is some aspects of the plot, and the way the countries of China and France are referred to by some characters in the story, that tread dangerously close to being Xenophobic in some areas, even for an "adventure" book.
In conclusion, read Cussler and Conan Doyle separately, but don't read Bell. I gave the book one star: I was being too generous.
