Seriously, I have to ask, where was your editor, Ben?
This could have been a very enjoyable book. Certainly the plot was exciting and intriguing, although you needed to suspend disbelief on occasion. For example, even with the support of the Prison Governor, Danny seemed to be able to get a day release from prison remarkably easily - with no restrictions on his movements.
However, for me what really marred the book was the plethora of errors - spelling errors, grammatical errors and plot errors - that appeared throughout the book.
Clearly, this book was not properly edited and, if you are a bit pedantic (as I know I am) and even if you aren't, but still expect to receive the quality that you pay for, you will find yourself growling at this book, as you read about the hero being `leant' some money; ordering half a pint of `larger' and running `passed' several things - and even finding an example of a greengrocer's apostrophe (as the runner's come hurtling round...)! You may also find yourself growling as races are changed from the fifth to the fourth without explanation; jockey's horses are changed; arriving at 4.38am for a meeting set for 4 am 8 pages earlier is described as being early... I'm sure you get the gist of what I'm saying!
My chief hint, Mr Osborne, would be, PLEASE! Get yourself a proper editor for your next book!
