He smiled coldly at Raymond. "One week from today. You'll have 90 minutes to diagnose the problem in front of qualified witnesses. When you fail—and you will fail—it will be documented permanently."
Preston turned to Beatrice, lowered his voice to a hiss: "If your son embarrasses this company, you'll never work in this city again. Not as a maid. Not as anything. I'll make certain of it."
Beatrice's face went gray. Her hands trembled. But before she could pull Raymond away, her son spoke.
"Mama." She looked at him: this strange, brilliant boy she had raised alone, this child who spent weekends in an old man's garage, this son who saw things others couldn't see. "I can do this," Raymond said. "Mr. Giuseppe taught me. I know I can do this."
Beatrice thought of every time she had told him to stay quiet, stay small, stay safe. She thought of his father, who died with dreams unfulfilled. She looked at Preston Whitmore's smug face, then she straightened her spine.
"My son doesn't lie, Mr. Harrington. If he says he knows, he knows."
The challenge was set: seven days.
News traveled fast through San Francisco's automotive community: a 13-year-old boy claiming to solve what defeated the world's best, the maid's son challenging certified experts. Preston made sure journalists knew about it; he wanted witnesses for the humiliation. He never considered that he might be wrong.
Five years earlier, on a sweltering August afternoon, an 8-year-old Raymond Nelson sat on the curb watching his mother cry. Their Honda Civic had died three blocks from her cleaning job: smoke rose from under the hood, the transmission warning light glowed angry red. Beatrice had already called two repair shops; both quoted over $600—money she didn't have, money that would take months to save. Missing work meant no paycheck, no paycheck meant no rent, no rent meant the street.
Raymond watched his mother's shoulders shake, watched her press her palms against her eyes, watched her whisper prayers to a God who seemed very far away.
"Mama," he said quietly, "can I look at it?"
She almost laughed. Almost. But something in his voice stopped her. "Baby, you're 8 years old."
"I know, but can I look?"
She had nothing left to lose. She popped the hood. Raymond stood on his tiptoes and stared at the engine: a maze of metal and rubber and mystery. He didn't understand any of it, but he wanted to.
The next morning, Raymond walked two miles to the Oakland Public Library. He found the automotive section and pulled every repair manual he could reach: Chilton guides, Haynes manuals, pages filled with diagrams and specifications. He understood maybe 10%, but he copied everything into a composition notebook, drew the diagrams by hand, and wrote questions in the margins.
