You will need a code to unlock:
Inside this dictionary, so thick and neat,
Lie words, definitions, a truly fun feat.
Read the words, let your eyes run free,
Find six, four, one - your lock's secret key!
Bouncing on pages, words play hide and seek,
Count the letters, it's the code you seek.
Six then four and ending with one,
Unlock the mystery, your quest is done!
*Feel free to take a book, leave one if you have. Same with the trinkets, take one & leave one for the next visitor 
.
If you could please try and make sure the container is locked again before you leave.
Have fun!
