And the FBI man said: "Sorry, Mr. Bending; I can't answer any questions. My job is over as soon as I deliver you."

A little later, Sam had another question. "Can you tell me where we're going, at least?"

"Oh—" the agent laughed, "sure. I thought I had. The General Post Office Building, on Kenmore Drive."

After that, Sam didn't say anything. That this whole affair had something to do with the Converter, Sam had no doubt whatsoever. But he couldn't see exactly what, and none of his wild speculations made sense.

He pulled up at last into the parking lot behind the Post Office Building. The second FBI man came up in the steel-blue Ford, and the three of them got out of the cars and went towards the building. It was quite dark by now, and the street lights were glowing against a faint falling of February mist. Bending, in spite of his topcoat, felt chilly.

They went in the back way, past the uniformed Postal Service guard, and took an elevator to the sixth floor. None of the three had anything to say. They walked down the hall, toward the only office that showed any light behind the frosted glass. The lettering on the glass simply said: Conference Room A-6.

The FBI man who had driven with Sam rapped on the door with gentle knuckles.

"Yes?" said a questioning voice from the other side.

"This is Hodsen, sir. Mr. Bending is with us."

The door opened, and Sam Bending felt mild shock as he saw who it was. He recognized the man from his news photos and TV appearances. It was the Honorable Bertram Condley, Secretary of Economics for the President of the United States.
