Sorry but I couldn't finish this - too many things annoyed me. For a start if a book is set in England surely it should use English terms, such as "footpath/pavement" instead of "sidewalk", and "waistcoat" rather than vest. People who help others are "aides" not "aids". And the phrase is "quid pro quo" not "Quid quo pro". Then there are the lack of apostrophes in places....
If you can put up with these inconsistencies and inaccuracies then it is probably a good read. For me, the annoyances outweighed the enjoyment of the story.
