It didn't take long for Sam, Colonel Gregson, and the Brigadier to find out that it wasn't easy to get to your feet when the ground beneath you is doing its best impression of Jell-O. After many attempts and several frustrated exclamations they managed to reach a standing position and keep it.

Despite the bizarreness of the situation, the old Brigadier seemed to be having the time of his life.

"I say, Gregson," he said to his comrade, "This is rather like the old days, isn't it?"

The Brigadier lost his balance and Colonel Gregson grabbed the back of his shirt-collar to stop him from falling.

"It certainly is, Sir," he replied.

Sam shook her head. Brigadier Collins' antics were ridiculous. Here they were, probably in danger, and he was behaving like he was sitting comfortably at home chattering away about "the good old days." It was time to change the subject.

"It must be some kind of earthquake," Sam said as she looked around.

Brigadier Collins shook his head in disagreement.

"That's doubtful, Major," he said. "This isn't an earthquake zone: why else do you think Stonehenge is still standing? No, it must be something else."

"Like what?"

The ground shook even harder, throwing them off balance but Colonel Gregson kept them from falling.

"I believe…" the Brigadier began thoughtfully.

He never got a chance to state his idea, for all of sudden Colonel Gregson shoved them away, urgently shouting: "Move!"

Sam and Collins stumbled forward and fell clumsily onto the grass. Something incredibly heavy hit the ground behind them, temporarily turning the earth into a trampoline which sent both Major and Brigadier soaring into the air. They hit the hard ground for a second time, emitting twin groans of pain.

They looked over their shoulders, and their mouths fell open to utter soft exclamations of horror.

Where Colonel Gregson had been only seconds ago, there was now a massive slab of rock. It was then that Sam and Brigadier Collins both realized the awful truth:

Stonehenge was falling down.

In an instant state of fear, Sam and Collins scrambled to their feet and began to run, dodging the gigantic stones that were tumbling all around them. Oftentimes Sam dragged the old Brigadier along as she steered the both of them around the massive hazards.

Sam froze mid-step as a rock crashed to earth only a foot away from her. Collins' grip on her hand became more strained and she looked over to see that the old man had fallen, sprawled out on the grass. His fingers clinging to Sam's hand kept his torso suspended in mid-air, but seeing that he now had Sam's attention, he let go. Collins gave an apologetic smile and began to haul himself back up to his feet with Sam's help.

That was when things went from bad to worse. Much, much worse.

Since both were focused on getting Collins back on his feet, neither of them remembered to watch the unstable pillars of Stonehenge. Before either of them could move away, one of the giant stones tilted and fell, landing less than a foot away from Sam; and right on top of Collins' legs.

The Brigadier screamed – an ear-splitting, horrible noise composed of the worst pain imaginable. Collins thrust Sam away, his fingers scraped the earth as his agony drove him mad and he tried to drag himself out from underneath the several-ton rock, still screaming.

Sam tried to help, but if she moved her hands away from her ears for just a second it felt like her head would explode. She could only watch the unfortunate man's pitiful attempts to free himself.

Eventually his screams quieted to desperate sobs, and Collins' arms stopped their pulling and lay on the grass, trembling with fatigue. Tears stained his cheeks and dripped off the ends of his moustache.

Sam moved her hands off her ears and grabbed the Brigadier's arms, preparing to try what he had failed to do. She never got a chance to, for just then Collins looked up her with bloodshot gray eyes and whimpered,

"Don't."

Sam's arms fell limply to her sides, and sympathetic tears began to blur her vision. She blinked rapidly, trying to clear them away.

"What can I do?" she asked.

"Get out of here," Collins replied hoarsely, "Wait until the 'quake's over. Then come get me."

"I can't leave you," Sam argued.

"Major, please," the Brigadier panted, his face white with pain, "You stay, you die, it's as simple as that! So go; now!"

"Sir-"

"Major!"

Sam stood up, but still she hesitated.

"Go," Collins said weakly, his old gray eyes looking up at her urgently, "Please."

Sam turned and ran. If the woman had bothered to look back, she would have seen Collins disappear in a bright flash of white light.
