The port lock opened. Talking ceased abruptly, as everyone turned. A black-clad Martian official, a Province Leiter, stood framed against the bleak sunlight, staring around the ship. Behind him a handful of Martian soldiers stood waiting, their guns ready.

"This will not take long," the Leiter said, stepping into the ship, the soldiers following him. "You will be allowed to continue your trip shortly."

An audible sigh of relief went through the passengers.

"Look at him," the girl whispered to Thacher. "How I hate those black uniforms!"

"He's just a Provincial Leiter," Thacher said. "Don't worry."

The Leiter stood for a moment, his hands on his hips, looking around at them without expression. "I have ordered your ship grounded so that an inspection can be made of all persons aboard," he said. "You Terrans are the last to leave our planet. Most of you are ordinary and harmless— I am not interested in you. I am interested in finding three saboteurs, three Terrans, two men and a woman, who have committed an incredible act of destruction and violence. They are said to have fled to this ship."

Murmurs of surprise and indignation broke out on all sides. The Leiter motioned the soldiers to follow him up the aisle.

"Two hours ago a Martian city was destroyed. Nothing remains, only a depression in the sand where the city was. The city and all its people have completely vanished. An entire city destroyed in a second! Mars will never rest until the saboteurs are captured. And we know they are aboard this ship."

"It's impossible," the heavy-set business man said. "There aren't any saboteurs here."
