"There's another thing," added Linda, slowly. "I'd want to start today. Because I must go to Kansas City as fast as I can." And she explained to Louise her plan about establishing Ted's alibi.

Louise leaped into the air in her excitement and approval.

"That's great! You know me, Linda—I always hate to wait about anything. We can pack our suit-cases and send our wires in an hour if we hustle. Hurry up! Hop in for a dip, and come right back!"

Ten minutes later they dashed breathless and wet into the dining-room of the Carlton bungalow, where Miss Carlton was eating a leisurely breakfast. In their excitement over their idea they could scarcely explain it. But at last the older woman understood; she heard them out, and gave her rather reluctant consent.

"If you don't make the trip too long," she added.

"A week?"

"Isn't four days enough? Then we would have to arrange only two stopping places—the same one coming back. And I am sure I could do that very easily."

The girls agreed, delighted even with a compromise. Nothing they had ever done promised to be half so thrilling.

They would fly southwest, making their first stop Kansas City, where Ted's firm was located. Searching through her address-book, Miss Carlton remembered that she had a cousin living in a hotel in that city and she wired her immediately to reserve a room for the girls for that night, and to chaperon their visit.
