I opened the door at that, and both of them started. Mr. von Inwald was standing with his arms folded, and Mr. Pierce had one arm raised holding up a glass of spring water. In another second it would have been in the other man's face.

I walked over to Mr. Pierce and took the glass out of his hand, and his expression was funny to see.

"I've been looking everywhere for that glass," I said. "It's got to be washed."

Mr. von Inwald laughed and picked up his soft hat from the table.

He turned around at the door and looked back at Mr. Pierce, still laughing.

"Accept my apologies!" he said. "It was such a fine wine, and so expensive."

Then he went out.
