“We must be very careful not to drop the shavings. The curator would make a terrible row about it. Now that we seem to be alone, with a knife in our possession, we might cut this portrait out of its frame and you could take it home to study at your leisure. Rolled up, you could carry it right out of the front door, and the newspapers would have a seven days’ wonder, the stolen Sargent! There! Not a bad job if I do say it myself.”

“Give it to me!”

“I beg your pardon.”

“Thank you,” she said, and turned away.
