Indy paused as Shay spoke up, something was off and she wasn't acting right. She wasn't even answering his question, but Indy ignored her response and continued with his lecture. "It shows that the ground had been dug up in those darker areas, and the roots of the plants were able to penetrate the tough layer of chalk that's just beneath the topsoil. In September of twenty-three, Crawford and Passamore began studying these darker areas, using the pictures as their only guide. They discovered the exact entrance to the ruin and a straight road which reached nearly to Salisbury, eight miles to the north. Stonehenge may be the first archaeological site anywhere that has taken advantage of aerial photography. I'm sure we'll see a lot more of its use in years to come. But we can thank the Royal Air Force for furthering our knowledge of Stonehenge." 

He noticed Shay was still not acting right, but he kept going on. As class came to an end, Indy said that next time he would be talking about Stonehenge. "We've already discussed menhirs and dolmens, and now you can add trilithons to your vocabulary. Your assignment is to read all the articles titled 'Excavations at Stonehenge' by Colonel William Hawley that have been published in the [i]Antiquaries Journal[/i] since 1920. Hawley as you know, is the archaeologist in charge of the current digging at Stonehenge. We'll talk about what he has found so far and the implications. Class dismissed. And don't forget, there will be a deadline for getting your topic approved for your term paper."

As the students filed out of the room, Indy put his glasses away, gathered up his notes, and thought about what he would say to Shay. When everyone cleared out, Indy grabbed his fedora was ready to walk out when he noticed Shay's messenger bag sitting alone at her desk. She must have left it by accident, Jones thought so he picked it up on his way out. 

He searched outside until he found Shay lying down on the grass. He walked over to her and squat down next to her placing her bag by her side. He was quiet as she still looked out of it. "I found this at your desk..." He glanced up to see a man sitting down on a bench turn away a look to his newspaper. "Shay, what's going on?" he asked.
