I could not work out who this book was aimed at.The book explains the type of cryptic clues and provides a list of words which to look out for in different types of clues. However there are no practice clues or practice crosswords to do to check your understanding. After you complete the section on the cryptic clues all there is a bunch of word lists which might be useful but are near impossible to navigate easily on kindle and could likely be brought up by doing an internet search. I returned the book and found another one half the price which in my opinion contained much more detail on the type of clues and gave you a chance to test your understanding as it contained clues for you try with explanations and answers. Considering the price of this book I just expected it to be better and feel that there are much better alternatives for someone wanting to learn how to do cryptic crosswords.
