If you just want something to read which is not too hard but poorly written then I recommend it.
I did find it interesting but it doesn't lead to anything spectacular. This book is a great reminder of some of the historical cases that took place in the UK however you may or may not form your own opinions of Dr Shepherd. His account of his life with his family may irritate you as it did with me but his account of his career was interesting. As he quotes in the book of being questioned in court as being arrogant Is actually what I think overall of this book.
