the note

on the door, there was a note. on the note, there were words, which said,"in the 3rd you'll find the key. the key has your destiny. take the key to the 15th door, there you will find some more." Erica was never good at deciphering codes, but she knew this code meant something. she couldn't find her mother anywhere. she had search all the floors of there small London apartment, and all of the nearby streets. she hadn't found a single sign of anything. she knew for a fact that this code had something to do with the location of her mother. Erica ran into the two-bedroom apartment and grabbed her emergency bag. she ran off. and she didn't know if she was coming back.
