“If I had my way,” said Archie, “I’d ride in the machine with her. But it’s against the rules. If they carry a passenger, they’re disqualified. They have to fly alone. That Weiner accounting fellow explained that it wouldn’t be fair to the others if the passenger helped drive.”

“We’ve got to find a better way to keep an eye on her,” said Bell. “Once the race starts, it will be a simple matter for Frost to lie in wait along the route.”

“I plan to post men on the roof of the support train with field glasses and rifles.”

Bell shook his head. “Have you seen all the support trains in the yard? You could get stuck behind a traffic jam of locomotives blocking the tracks.”

“I’ve been considering a team of autoists to run ahead.”

“That will help. Two autos, if I can find the men to drive them. Mr. Van Dorn’s already complaining that I’m gutting the agency. Who is on this machine approaching? The green pusher?”

“Billy Thomas, the auto racer. The Vanderbilt syndicate hired him.”

“That’s a Curtiss he’s driving.”

“The syndicate bought three of them, so he can choose the fastest. Six thousand apiece. They really want to win. Here comes a Frenchman. Renee Chevalier.”

“Chevalier navigated that machine across the English Channel.”

Bell’s eye had already been drawn to the graceful Blériot monoplane. The single-wing craft looked light as a dragonfly. An open girder of strut work connected the cloth-covered wings to the tailpiece of rudder and elevators. Chevalier sat behind the wing, partially enclosed in a boxlike compartment that shielded him nearly to his chest. He was switching his Gnome rotary engine on and off to slow it as he landed.

“I’m buying one of those when this job is over.”

“I envy you,” said Archie. “I’d love to take a crack at flying.”

“Do it. We’ll learn together.”

“I can’t. It’s different when you’re married.”

“What are you talking about? Lillian wouldn’t mind. She drives race cars. In fact she’ll want one, too.”

“Things are changing,” Archie said gravely.

“What do you mean?”

Archie glanced around and lowered his voice. “We haven’t wanted to tell anyone until we’re sure everything’s O.K. But I’m not about to start a dangerous new hobby now that it looks like we’re going to have children.”

Isaac Bell grabbed Archie underneath the arms and lifted him joyfully off the ground. “Wonderful! Congratulations.”

“Thank you,” said Archie. “You can put me down now.” People were staring. It was not often they saw a tall man raise another high in the air and shake him like a terrier.

Isaac Bell was beside himself with happiness. “Wait ’til Marion hears! She’ll be so happy for you. What are you going to name it?”
