“And then what?”

“Then he turned the paper over,” said Mr. Gubb, “and he says, ‘Now, please sign this one.’ So I signed it.”

“Under Mr. Bilton’s name again?” said the Judge.

“Why, no,” said the paper-hanger detective. “Not under it, because it wasn’t located nowhere to have an under to it. Mr. Bilton hadn’t signed on that side yet.”

There was an instant sensation.

“Bilton hadn’t signed that side?” said Mr. Higgins. “Which side hadn’t he signed?”

“The other side from the side he had signed,” said Mr. Gubb.

“Did you notice which side he had not signed?” insisted Mr. Higgins. “Was it this side that mentions Mrs. Doblin, or this side that mentions Mrs. Kinsey? Which was it?”

Mr. Gubb took the paper and examined it carefully. He turned it over and over.
