Analysis Summary
- LIMITED ANALYSIS (15 reviews) With only 15 recent reviews available, we can only detect the most obvious manipulation patterns.
- The available reviews don't show obvious signs of manipulation, but more reviews would provide better analysis. Recommendation: With limited recent reviews, also check older reviews manually and look for products with more reviews if possible.

Most Helpful Review
"This book was written - better: cut-and-pasted with a few changes here and there to cover the tracks - with no other purpose than to line Ms Taggart's and Mr Scrivenor's pockets. (Somehow I have the nagging feeling that Patrick Scrivenor is just Ms Taggart hiding behind a pseudonym; or is that just my irk at being conned out of my lolly?). Had Ms Taggart added a few pages to "My Grammar and I" this book would have been of a complete superfluity. But to be asked to fork out 10 quid for more of the same is not 'nice'."
