The King's Quest II Hintbook was the official Sierra hintbook for King's Quest II.
Like the original King's Quest I Hint Book, following the hints in the Hintbook will often lead you down the worst (more violent) solution path, as the main path through the game. Such as killing the snake rather than helping it out with the bridle. The good solutions are either discussed in questions much later in the book (with the author mocking the reader for not discovering it on their own), or left over as things to 'try'. This was intended to keep the better solutions as a surprise (and to also punish the reader for simply reading through the questions).
There are also a number of false questions to throw of people who try to simply read through the book.
