“Yes, his radio detector. That was a disgrace. Some unscrupulous person stole it.”

“And sold it to a foreign country. He doesn’t want that to happen again.”

“But, Barbara, they don’t use parachutes on a ship.”

“On this one they do. Shush!” Barbara held a finger to her lips. “Don’t ask me another thing about it.”
