Tricky Tomes is a puzzle in Professor Layton and the Last Specter.


Here is a bookshelf crammed with thick, heavy encyclopedias arranged as shown. All the books have the same depth, and they fit perfectly onto the shelf.

There is one book that nobody ever takes from the shelf first, no matter who is browsing the shelf. Touch which book that is.

Think about the puzzle carefully. When it says there is one book that nobody takes from the shelf first, it actually means there is one book that nobody can take first.

Think about the process of taking a book from a shelf. You can grab it and pull, hood the spine with a finger and pull, or push it in to try to get leverage on it.

If there a book you cannot remove using these actions?

Say you have a book placed between two other books. If the two books on either side are shorter, then you can grab the top of the middle book to pull it out. Books 3 and 5 are like this, so they can be taken out first.

Similarly, the books that have a gap between the top of the book and the shelf above can be hooked out from the spine. All the books except 3 and 8 are like this, and so can be taken first.



Too bad!

Do you notice anything odd about the bookshelf?



Encyclopedia number 8 is the only book that cannot be taken out first. There is no way to get it out without removing another book first.
