Most of the puzzles and treasure hunting in can be time-consuming. One of the more accessible treasures to locate are those contained within the Decorated Keyhole Chests. All of these chests are in the general Library area of the Castle and all can be opened with the Bunch of Keys that are also found in the Library as well.

While Leon is able to come and go from the Library during the Castle portion of the game, the Decorated Keyhole Chests can only be collected during the short portion of the game when playing as Ashley.

These chests can only be opened while playing as Ashley and the keys will not carry over to Leon, so be sure to grab everything.
