Mason shoved the ad across the counter. “Here,” he said, “is a fifty-dollar bill. Keep this ad running until the money’s used up or until I tell you to stop. Run it in display type, or double-space it, or whatever is necessary to attract attention.”

“Yes, sir,” the girl said, looking at his wet clothes. “It must be raining outside.”

Mason shivered, passed one of his cards across the counter. “Any replies you receive,” he said, “are to be sent at once by airmail to this address. Do you understand?”

“Yes, sir.”

“Good night,” Mason said, and strode out into the cold rain. “If I can’t buy an overcoat,” he told the cab driver, “perhaps I can find an airplane that will carry me far enough south to get into a different climate.”

The cab driver looked at him in amazement.

“In other words,” Mason said, “the airport, and make it snappy.”

At the airport, Mason found that the next regular passenger plane left Seattle at ten-thirty-five the next morning. The taxicab took him to one of the city’s better hotels where he again registered and explained to the clerk that he had no baggage.

In his room, Mason enjoyed the luxury of a hot bath and a night’s sleep. In the morning, he called Della Street on the long distance telephone.
