Dazedly, Biff and the other boy reached the gate. They presented their tickets. The attendant looked from one to the other.

“Twins?” he asked, a smile on his face.

Still apparently unable to speak, the boys shook their heads.

They walked across the apron leading to the waiting aircraft. As they walked along, side by side, each cast quick, questioning glances at one another.

It was unbelievable!

The boys were the same height. Both were broad of shoulder. Both carried their well-muscled bodies with the grace and posture of the trained athlete.

The only immediately noticeable difference distinguishing the boys was their clothing. Biff was hatless, as always. The other boy wore a hat. Biff wore light gray slacks, a soft sleeveless sweater, and a loose sports coat. His double wore a tight-fitting, dark-blue suit and a white, high-collared shirt. His clothes were as formal as Biff’s were informal.

They mounted the loading ramp and entered the plane. The stewardess gave them the same interested, friendly look the gate attendant had given them.

“I’m sure you two will want to sit together,” she said. “You’re twins, aren’t you?”

“No, ma’am,” Biff gulped.
