"No—I heard nothing and saw nothing: I've no idea where they are."
Wedgwood considered this information during a moment's silence, during which Nottidge watched him anxiously, as if wondering what conclusion he had come to.
"Do you take in the letters at Mr. Levigne's?" asked the detective, suddenly turning to Miss Robinson. "Or are they dropped into a locked box?"
"They're dropped into a box, but it isn't locked. I take them out of a morning, and at any other time, and if Mr. Levigne's at home I take them to him. If he isn't I give them to Miss Monniment—if she's in. If she isn't, they're put in Mr. Levigne's study."
"Do you know Miss Monniment's handwriting when you see it?"
"Yes, well enough!"
"Very well," said Wedgwood. "Have you seen it on any envelope since she went away—any envelope addressed to Mr. Levigne?"
"I can't say that I have," replied Miss Robinson. "I may have done, you know."
"Keep a sharp look-out for any letter in her handwriting," commanded the detective. "If you see one, note down the postmark! And then drop a card to Mr. Nottidge giving particulars of the postmark. Understand?"
