"Put it away! Put it away at once!" said Lupin very smartly.

"You're not to use it.

"Here! Stand here!" cried Lupin, raising his voice.

And he caught the policeman's arm, and hustled him roughly to the front of the doors of the lift-well.

"Do you see these doors?
Do you see them ?" he snapped.
"Yes, yes," said the policeman, glaring at them.
"They're the doors of a lift," said Lupin.
