Part 2: The Postmark Changed the Room
Once Dr. Kemp read the year out loud, the whole basement lost its rhythm without actually going silent. Kids still stood at the tables. A parent still twisted the cap back onto the lemonade jug. The old fridge kept buzzing by the refreshment table. But every voice after that came out slower, like people were testing the floor before putting weight on it.
Dr. Kemp held the postcard by two corners and looked at Eli. “Where did you get this?”
Eli shrugged one shoulder. “It got to me.”
“That’s not an answer,” I said.
He looked at me then, finally direct, and said, “You asked for something you could touch.”
That was rehearsed too. Same clipped tone. Same feeling of a line dropped into place.
Mason was still beside the coil bench with the alligator clips in his hand. He had gone from loud to careful in under a minute. Tasha had lost some of her volume too, but not enough to stop talking.
“Maybe this is some family thing,” she said, glancing at the postcard and then at me. “But you can’t have students caught in the middle of it.”
“Then stop using his words like facts,” I said.
Dr. Kemp lifted a hand before Tasha could answer. Keys flashed in her grip. “Everybody back to your tables unless you’re directly involved. Nina, Mason, Eli, stay here. Tasha, give us a minute.”
Tasha did not like being moved, but she stepped back toward the old fridge and stayed close enough to hear.
I set my clipboard on the bench and pointed at Mason. “Tell Dr. Kemp what cabinet you mean.”
He cleared his throat. “The one by the supply cage.”
“Color,” I said.
“Gray.”
“How many doors?”
He looked at the cabinet, then at me. “Two.”
The cabinet by the supply cage has one sliding panel and a padlock loop we almost never use. Dr. Kemp knows that as well as I do. Her eyes moved to it and stayed there for a second too long.
“What’s in it?” I asked.
“Components.”
“Which ones?”
He licked his lips. “The stronger ones.”
“What does that mean?”
He tightened his fingers around the clips so hard they clicked. “The stronger parts.”
I did not raise my voice. “Who told you to call it the north cabinet?”
He looked at Eli again.
Not long. Just enough.
Dr. Kemp saw it this time. So did Tasha, because I heard her shoes stop against the concrete.
“Mason,” Dr. Kemp said, “answer Nina’s question.”
He shifted his weight and stared at the floor drain between the benches. “I just heard it called that.”
“By who?”
He took too long. “Around.”
“Around where?” I said.
He had no place to put that answer. His mouth opened, then closed on nothing.
Eli stepped in before the silence could finish its work. “This is ridiculous. He doesn’t need a vocabulary quiz to tell you what happened.”
“No,” I said, “but he does need to know what he’s accusing me of.”
Eli gave a short laugh with no smile in it and reached for the postcard. Dr. Kemp pulled it back first.
That was another small turn in the room.
She looked down at the writing side again. I stayed where I was and read it upside down over her hand. There were only three lines besides my nickname. The first said, Told you you’d stop at the wrong word. The second said, Don’t let him make the kid do it twice. The third was signed with a single letter: E.
I said, “Read it out loud.”
Eli’s head came up fast. “Don’t.”
Dr. Kemp’s eyes moved over the card again, slower this time. She did read it out loud. Not to the room, exactly. More to the air between the five of us. But people heard. People always hear what they are not supposed to.
By the time she got to the line about the wrong word, Tasha had stopped pretending this was just me making a scene. Mason’s face had gone flat and bright at the same time, like all the blood had rushed up too quickly.
“What kid?” Dr. Kemp asked.
Nobody answered her right away.
I did. “Him. Mason.”
Then I pointed at Eli. “And if that signature is supposed to be yours, you knew this line was wrong before he said it.”
Eli held out his hand for the postcard. “Give me that.”
Dr. Kemp did not. “Why does this card say not to let him do it twice?”
Mason took one step back from the bench.
The folding chair behind him scraped hard across the concrete. Every head in the nearest half of the basement turned toward us. Eli moved then, quick enough to make it clear the stillness from before had been chosen. He was not reaching for Mason. He was reaching for the card.
I got there first and put my hand over the bottom edge while Dr. Kemp still held the top.
“No,” I said. “He can explain the north cabinet. Or Eli can explain why a postcard with a postmark from four years ahead says he already knew Mason would use the wrong word.”
Nobody in that basement had an easy sound left after that. Even Tasha stayed quiet. Mason looked at Eli like he was waiting for the next line and not getting it, and Eli looked back at him for one beat too long before saying, very carefully, “Put the card down.”
That was the moment I knew the postcard was not the only thing he had brought into that room ahead of time.
