I have a puzzle: the book is Harry Potter and the deathly hallows. the first letter in each group is which word, and the second letter is which letter in that word. e.g. (16, 5) is the 5th letter in the 16th word. you count the words from the start of chapter one, not including the chapter title. here are the numbers: (19, 3) (4, 1) (4, 2) (10, 1) (37, 1) (4, 5) (4, 6) (8, 1) I will follow the first person to comment the word
