“And also,” said Gray still more dryly, “to mention that the partitions here are very thin and that I heard all of the conversation just now.”

“I guess I’ve got to try,” said Cunningham grimly. “But I wish I knew what to do.”

These people are scared. That’s why they killed that man we saw on the train. And they will be worse scared of Vladimir. He hasn’t gone, and if I can read faces he’s planning devilment for them. I tell you there’ll be wholesale killings in the hills unless you go up there! Stay with them. Argue with them. Educate them if you must. But keep them from killing anybody!”
