HOW TO GET INTO THIS BOOK.
Project Gutenberg EPUB3 edition
Knock at the Knocker on the Door, Pull the Bell at the side,
Then, if you are very quiet, you will hear a teeny tiny voice say through the grating “Take down the Key.” This you will find at the back: you cannot mistake it, for it has J. J. in the wards. Put the Key in the Keyhole, which it fits exactly, unlock the door and WALK IN.
