The next day at school, I didnโt wait for Jameson to find me. I found him. โWhat if the numbers arenโt dates?โ I said.
That got me a slow, winding, wicked smile. โHeiress, you took the words right out of my mouth.โ
I half expected to end up back on the roof, but this time Jameson took me to one of the โlearning podsโ in the STEM Center. Basically, it was a small, square room where the walls, ceiling, and floor were all painted with whiteboard material. There were two white rolling chairs in the center of the room, and nothing else.
Eli started to follow us inside, and Jameson took that as his cue to run a hand down my back and bring his lips to the spot where my neck met my jawline. I arched my neck, and Eli went bright red and stepped out of the room.
Jameson shut the doorโand went to work. There were five dry-erase markers attached to the back of each of the rolling chairs. Jameson grabbed one of the markers and began writing on the wall directly in front of the chair. โEight, three, seven, five,โ he said.
I rattled off the next four numbers from memory as he continued writing. โNine, seven, four, eight.โ
Writing the numbers without the dashes freed up countless possibilities. โA passcode?โ I asked Jameson. โA PIN number?โ
โNot enough digits in either of them for a phone number or a zip code.โ Jameson stepped back, sat down in one of the chairs, and pushed off. โAn address. A combination.โ
I flashed back to the moment when he and I had stepped off a helicopter, with a different sequence of numbers. The air between us had felt electricโ just like it did now. Weโd been flying highโand thirty seconds later, heโd gone cold.
But this time was different, because this time we were on the same page. This time there were no expectations. I was in control. โCoordinates,โ I said. That had been one of Jamesonโs suggestions, the last time around.
He turned the chair and, with a push of his heels, came skidding back to me. โCoordinates,โ he repeated, eyes alight. โNine-seven-four-eight. Assuming the numbers are already in the correct order, nine has to be the number of degrees. Ninety-seven is too big.โ
I thought back to my fifth-grade geography class. โLatitude and longitude run from negative ninety to ninety.โ
โYou two donโt know the valence of any of the numbers, obviously.โ Jameson and I whipped our heads back toward the door of the pod.
Xander was standing there. I could see Eli, still red-faced, behind him. Xander stepped into the pod, shut the door, and, with no hesitation whatsoever, leaped forward to flying-tackle Jameson to the ground.
โHow many times do I have to tell you?โ the youngest Hawthorne demanded. โThis is my game. No one is solving this without me.โ He plucked the marker from Jamesonโs hand and stood. โThat was a friendly tackle,โ he assured me. โMostly.โ
Jameson rolled his eyes. โWe donโt know the valence of the numbers.โ He echoed the last thing Xander had said pre-tackle. โAnd we also donโt know which is latitude and which is longitude, so nine degrees could be nine degrees north, south, west, or east.โ
โEight-three-seven-five.โ I grabbed another marker off one of the chairs and underlined the numbers on the board in different combinations. โThe degrees could be eightย orย eighty-three.โ
Jameson smiled. โNorth, south, east, or west.โ โHow many total possibilities?โ Xander mused.
โTwenty-four,โ Jameson and I answered at the exact same time.
Xander gave us a look. โIs there something going on here that I should be aware of?โ he asked, gesturing between the two of us.
Jameson shared a brief look with me. โNothing of note.โ He said
nothingย like it wasย something.
โNone of my business!โ Xander declared. โBut for the record: You lovebirds are incorrect. There are way more than twenty-four possible locations here.โ
Jameson narrowed his eyes. โI can do the math, Xan.โ
โAnd I can humbly inform you, big brother, that there are three different ways of listing coordinates.โ Xander grinned. โDegrees, minutes, seconds. Degrees, decimal minutes. And decimal degrees.โ
โWith only four digits,โ Jameson insisted, โweโre probably looking at decimal degrees.โ
Xander winked at me. โButย probablyย is never good enough.โ
โPacific Ocean,โ Jameson called out, and I wrote the location next to the designated coordinates. โIndian Ocean. Bay of Bengal.โ
Xander picked up right where his brother had left off. โArctic Ocean.
Arctic Ocean again!โ
Both of them were entering coordinates into a map search. My brain kicked up a gear with each location they called out.ย The Arctic.ย That couldnโt be where this clue was supposed to point us, could it? And that was assuming that these numbers were coordinates at all.
โAntarctic Ice Shield,โ Jameson offered. โTimes four.โ
By the time we were finished, the number of actual, non-arctic land locations on our list was much smaller than Iโd expected. There were two in Nigeria, one in Liberia, one in Guinea, and one inโฆ
โCosta Rica.โ I said out loud, unsure at first why that location was the one that had jumped out to me, but a moment later, I remembered the last time Iโd read the wordsย Costa Ricaโin the binder.
โYou have that look on your face,โ Jameson told me, his lips quirking upward. โYou know something.โ
I closed my eyes and focused on the memory, not his lips. Skyeโs bequest had led to True North, one of the Hawthorne familyโs many vacation homesโmine, now. I tried to remember the pages Iโd flipped through the night of the auction.ย Patagonia. Santorini. Kauai. Malta. Seychellesโฆ
โCartago, Costa Rica.โ I opened my eyes. โTobias Hawthorne owned a house there.โ I pulled out my phone and looked up the latitude and longitude of Cartago, then turned my phoneโs screen toward the boys. โItโs a match.โ
I tried to remember what the Cartago house looked like, but all I could see in my mindโs eye was the surrounding vegetation and flowers, lush and bright and larger than life.
โWe need to go to Costa Rica.โ Xander didnโt exactly sound put out about that.
โI canโt,โ I said, frustrated. Iโd had to fight to go to Colorado. There was no way that Oren and Alisa would sign off on international travelโnot when I could only spend two more nights away from Hawthorne House this month.
โXanderโs not going anywhere, either.โ
For a second time, I found myself turning toward the doorway of the pod. Thea stood there.
โAre you just lettingย anyoneย in?โ I called to Eli.
The reply I got was muffled, but I made out the words โnot my job.โ
โRebecca needs you,โ Thea told Xander. For the first time since Iโd met her, she wasnโt wearing any makeup. She looked almost mortal. โShe didnโt come to school today. Itโs her mom. I know it is. Rebecca wonโt answer my calls, so itโs going to have to be you.โ It was clearly killing Thea to ask him, but there she was.
I expected Xander to put up a fight. How many times had he said that this wasย hisย game? But Xander just stared at Thea for a moment, then turned back to Jameson. โI guess youโre going to Cartago.โ
Jameson glanced at me. I was fully prepared for him to ask me for another plane. Instead, the expression on his face shifted. โCan you call Libby and Nash?โ
