The Note in the First Edition
A bookseller hides a thank-you note inside one of four display books: a novel, an atlas, a poetry collection, or a field guide. Four colored bookmarks show the display order, and the closing notes reveal which book contains the message.
Your task
Which book contains the thank-you note?
- 1
The note is not in a book with a red or blue bookmark.
- 2
The field guide was sold before the note was written.
- 3
The poetry collection has the gold bookmark.
- 4
Only one display book contains a note.
Solution revealed
Solution
The answer: Poetry collection
The red-bookmarked novel and blue-bookmarked atlas are ruled out directly. The field guide had already been sold when the note was written, so it could not contain the message. That leaves the gold-bookmarked poetry collection as the only possible book.
