The runabout turned and slipped along cautiously to the rear, watchful for byways. At the cross-road McGuire was out again. His match, held close to the mud and gravel, revealed the tread of familiar tires.

"All right, sir," he briefly reported. "The other edition went this track."

With a twist of the wheel Benton was again on the trail. Back in the side lane stood a car in which a girl sat alone, solemnly indignant.

"Cara!" Benton was standing on the step. His voice was tremulous with solicitude and perplexed anxiety. "Cara!" he repeated. "What does it mean?"

"I don't know," she responded coolly. "Something seems to be broken."

"I don't mean that." McGuire was already investigating. "What does it mean?"

She sighed wearily.

"When I foolishly agreed to play Juliet to your Romeo," she informed him, and her tones were frigid, "I didn't know that your Romeo was really only a Dromio. The other edition of you"—he flinched at the words, and McGuire choked violently—"is back there, I believe, hunting for matches."

"She's all right, sir," interrupted McGuire in triumph. "She'll travel now. It's only disconnected spark plugs and a short circuiting."

"Travel, then!" snapped Benton. "Leave the runabout here. The other gentleman may prefer not to walk home."
