BARTHWICK. What's that? The cigarette-box! Is anything else missing?
MARLOW. No, sir; I 've been through the plate.
BARTHWICK. Was the house all right this morning? None of the windows open?
MARLOW. No, sir. [Quietly to JACK.] You left your latch-key in the door last night, sir.
[He hands it back, unseen by BARTHWICK]
JACK. Tst!
BARTHWICK. Who's been in the room this morning?
MARLOW. Me and Wheeler, and Mrs. Jones is all, sir, as far as I know.
BARTHWICK. Have you asked Mrs. Barthwick?
[To JACK.] Go and ask your mother if she's had it; ask her to look and see if she's missed anything else.
