Moser gazed sadly down the hill. “I hate leaving her behind, but she says you’re going to help get her out.”

“Don’t you worry, we’ll get her out. And in the meantime, Dr. Ryder has promised that her treatment will improve, dramatically. Will your truck make it to Albany?”

“Yes, sir.”

“I’ll go ahead and charter a train. It will be waiting in the Albany yards, steam up for Belmont Park. Mechanicians will be standing by to help you reassemble the American Eagle the second you arrive.”

“Belmont Park? Are you intending to enter the American Eagle in the cross-country race?”

“No,” Bell laughed. “But it’s going to help me keep an eye on Josephine Josephs.”

Andy Moser looked incredulous. Of all he had read and heard since Isaac raced up in his Model K Ford, this took the cake. “You know the Sweetheart of the Air?”

“I am a private detective. Josephine’s husband is trying to kill her. The American Eagle is going to help me save her life.”

After Bell chartered his support train in Albany, he wired San Francisco to alert Dashwood to the fact that Marco Celere’s original name was Marco Prestogiacomo. He might well have still been Prestogiacomo when he landed in San Francisco, and Bell hoped that this new information would speed up Dashwood’s unusually slow progress.

“I’M NOT GOING TO WASTE flying time watching Dmitri Platov demonstrate his thermo engine,” Josephine told Isaac Bell a day later. “I doubt it will work. And even if it does, that horrible Steve Stevens is too fat to drive a flying machine, even one of Marco’s.”

“One of Marco’s? What do you mean?”

“It’s a biplane he invented for heavy lifting, to carry a bunch of passengers.”

Bell said, “I wasn’t aware that Marco had another machine in the race.”

“Steve Stevens bought it from his creditors. Lucky him. It’s the only machine in the world that will lift him. He paid twenty cents on the dollar. Poor Marco got nothing.”

Bell escorted her to her monoplane. Van Dorn mechanicians spun her propeller, and when the blue smoke of her motor turned white, she tore down the field and took to the sky for yet another of her long-distance practice runs.

Bell watched her dwindle to a yellow dot, secure in the thought that soon he would be flying beside her. The Eagle had arrived late last night on a four-car special train that Bell had chartered for the duration. Andy Moser and a Van Dorn crew were already trundling the pieces from the rail yard to the infield.
