I haven't found this book particularly clear. The text doesn't seem to follow a particularly logical sequence, and some terms are not properly referenced in the index.
For example 'Property Register' is briefly explained, but later when I couldn't remember what this was, I found it wasn't listed alphabetically in the index (eventually found it as a sub-listing under 'property developer', although the text actually says that developers DON'T need to keep property registers, landlords do).
Some of the text is also vague, which doesn't seem helpful for explaining tax law - eg. 'The taxman has 12 months from the previous 31 January to open an inquiry. If he is out of time, then he can't conduct an inquiry.'. Well, any date is within 12 months of a January 31st, so this doesn't make sense - so you'll need to try to second guess what the author really meant (maybe from the January 31st following the tax year in question..probably?).
I'd expect a book in this series to crystal clear and unambiguous, with all the terms clearly referenced, and unfortunately, it fell a little short.
