“For our teacher the trip ends soon. She might have found her end in an accident. Her companion might have planned it out before the trip began. I suspect the second traveler had been searching and fantasizing about ways to solve her own problem and when she saw an opportunity, she acted.
“At any rate, we must turn our attention to the other traveler, because the teacher can not long act. She takes over the teacher’s trips, even her identity. She uses the teacher’s credit cards, writes checks on her account and drives with her license. She enjoys a carefree summer while the teacher sets on ice somewhere.
“When the end of summer is in sight, so is a new problem. Our villain is an imaginative problem solver and an opportunist. She comes across a way to get rid of some troublesome baggage, disappear, and tangle potential pursuers in legends and jurisdictional problems.
“So when she got on the bus to begin our tour, she already prepared some transportation for herself in Joplin. She came out here, discarded her load, and went back to the hotel for a shower and change of clothes before getting on the bus. She might have had an accomplice to help her get around. She might have had a moped. It’s not as if she was really paying for anything.
“When we arrived here and people were settled in, she walked away. In ten or fifteen minutes, she could be a mile away, which might as well be a thousand miles away. She gets into the car she left or she meets her accomplice. She could have been well into Missouri or Kansas or Arkansas by the time we discovered the body. She may be gone for good.”
The sheriff gently shook his head. “That seems like a lot of work to get rid of a body. It’s a crazy story.”
“People do crazy things, sir. If someone is crazy enough to murder or hide a body for months, they might be crazy enough to do all kinds of things.”
“You have quite an imagination, Dr. Davis.”
“In my line, it’s a very helpful thing.”
