“Mateo,” Elena said softly. “Time.”

By the time they reached Matrix Reasoning , Elena had begun to suspect the problem wasn’t in his mind, but in the interface between his mind and the world.

Her client, a man named Mateo who listed his occupation as “architect,” nodded. He had requested the WAIS-IV evaluation himself. “I feel foggy,” he’d said on the phone. “Like the blueprints in my head have turned to scribbles.” He was only thirty-four.

Mateo’s hands trembled. He picked up a cube, turned it, put it down. He assembled two cubes correctly, then froze. Instead of rotating the pattern in his mind, he tried to force the physical blocks to match a memory that was no longer there. He pressed a white triangle against a red half-square. It didn’t fit. He pushed harder.

Arithmetic . “If a man buys twenty oranges for two hundred pesos and sells them for fifteen pesos each, what is his profit per orange?” Mateo’s brow furrowed. He started doing complex multiplication in the air with his finger. The answer was simple: five pesos. He said eight.
