The Sherlock Holmes Puzzle Collection - The Lost Cases

I acquired this book from a popular discount book store in the UK and still feel ripped off. I was hoping for a riddle/logic book but its just mostly math problems which I could in newspapers. Problems in this book can be hard and as another reviewer pointed out "wrong" but after a while I gave up on it (want to say moved on but I do think I'll come back to it - OCB). You won't learn anything from this book or get any entertainment from the sherlock script, just either discover you have the maths and patience to get through it or like me think its wasted money

The 1 star rating may seem too harsh, but the truth is, 90% of puzzles are purely mathematical and have nothing to do with Sherlock Holmes. They are presented by Holmes and Watson, but mostly you won't need any deductional or mystery solving skills, you simply have to know your maths. In addition to that, some of the puzzles are really easy, but some of them (even in the beginning of the book) are too hard, mainly because they do not make any sense, or their logic is faulty.Truth be told, the book is a nice piece in itself, looks good on the shelf, but that is all.
