After obtaining SECRET #2, as shown in the previous section, go to the small alcove opposite the entrance...
...and drop down into the room below. Don't use that switch yet. (If you already did, pull it again to return it to the up position. Using it drains the water below. If you drop down into the passageway when it's dry, you won't be able to reach the next secret.)
Move to the edge of the opening over the water and, if possible, shoot the crocodile (6) below. You may have to take a dip to get its attention. Then climb out of the water to shoot. If you want to, you can wait to kill it, but then you'll have to outswim it to reach the next secret.
Jump in the water, turn around to face the switch, then swim underneath the switch room and forward to a small opening in the ceiling.
If it hasn't been patched out in a future update, you'll notice a strange texture: a detail from The Letter by the 18th-century French painter Jean-Baptiste-Camille Corot. It's not solid, though. Surface in this opening.
Climb into the room above and pick up some shotgun shells (6). This is SECRET #3. (NOTE: If you don't already have the SHOTGUN, you'll get it here instead of the shells.) The other side of the flooded opening features more famous art: Girl with a Pearl Earring by the Dutch Golden Age painter Johannes Vermeer. I haven't had this much art education in a game since Horizon: Forbidden West!
DARK MODE: Even with brightness adjusted, dark images on a light background can be hard to see. May I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's web store.)
