I pull the door open. Inside…

Oh.

Normally, I’m not a material girl. Stuff doesn’t impress me.

But for a moment, I forget how to breathe. I relive one of my earliest memories, when Dev, who must’ve been pretty much a baby himself, blew in my nostrils, his stronger lungs overwhelming my own, leaving me gasping in shock.

I can’t believe what I’m seeing.

“Nemo’s treasury,” Ester says, remarkably calm. “I thought so.”

Now I understand the old saying all that glitters is not gold. Because in Nemo’s treasury room, a lot of the glitter comes from silver, diamonds, rubies, pearls, and crazy fancy jewelry. The shelves are lined with wooden chests, each overflowing with carefully sorted loot. Nemo was apparently obsessed with order. He has all the diamonds grouped together, all the rubies, all the pearls sorted by color and size. Against the far wall is a pallet of gold bricks. There’s even a shelf with half a dozen crowns, each of which looks like it might have been ripped from the head of some nineteenth-century monarch. All in all, the room reminds me of a bizarre supply store.

Excuse me, sir, where can I find sapphires?

Yes, those would be on aisle three, just past the silver-ingot display.

“Wow,” I say, which seems insufficient.

Ester looks around in awe. “This room was organized by a genius.”

Top sniffs around the treasure, wagging his tail half-heartedly as if to say, Well, I guess it’s all right, but it ain’t doggy treats.

Ester picks up a shoebox-size chest of white pearls. “Nemo gave Harding and Pencroft a box like this. It was enough to build the academy.”

“There must be twenty boxes like that in here,” I say.

Ester scans the room, probably running estimates. “Nemo gathered some of it from the merchant vessels he plundered, some from older shipwrecks he discovered. In 20,000 Leagues, he boasted that he could pay off the national debt of France and it wouldn’t make a dent in his fortune. This room may be just one of his stashes. Harding family legends say Nemo had supply bases hidden all over the world.”

I wonder if this is what Land Institute wanted, too, along with the technology: money. Such a common thing to want, but with this much wealth, they could probably build three more Aronnaxes and topple several world governments. Given the potential payoff, risking their brand-new sub and their senior class starts to sound like a solid gamble.

Thinking about it in those terms makes me want to take a shower.

My eyes fix on a strange-looking instrument propped in the corner. It’s about the size of a guitar, but with a keyboard instead of strings, alt-tech gears and levers where the fret board should be, even a dial that looks like a color wheel, maybe for special visual effects?

“What in the—?” I pick it up gingerly. “Captain Nemo invented the keytar?”

Ester laughs. It’s a rare, adorable sound, like a piglet being tickled. She doesn’t often find my jokes amusing (which keeps me humble), but absurdities get her every time. “He took his music seriously.”
