"Scotty, don't finish your job on that engine to-night. Let the new engineer adjust and time it after you finish in the morning. Then just before you come off slip this little ounce package in the gasoline tank."
Scotty grinned for the first time. "Will that do it?"
"In about half an hour his trouble will commence. It's a trick I learned in German shipyards."
Scotty grinned again.
"They think they know it all, especially about machinery, when, as a matter of fact, everything they have is stolen. It's their perverted, thieving ego, Scotty. They even murder more efficiently than anyone else."
Scotty laughed outright. "I wonder if they will have a different kind of hell or heaven?"
I felt sure of Scotty now, so I said, "Scotty, they know nothing about heaven. About hell, what they don't know now they will learn when America gets in the game. This very case may be the one to bring us in."
Scotty started to yell but I put my hand over his mouth. "Anyhow," he whispered, "I got one whoop coming to me later—eh?"
"You have, Scotty—stick tight, all ears and eyes, and no tongue." He stood grinning after me as I went my way. "I'll see you soon," I said in parting.
