MARLOW, No, sir.
BARTHWICK. This Mrs. Jones—how long has she been working here?
MARLOW. Only this last month, sir.
BARTHWICK. What sort of person?
MARLOW. I don't know much about her, sir; seems a very quiet, respectable woman.
BARTHWICK. Who did the room this morning?
MARLOW. Wheeler and Mrs. Jones, Sir.
BARTHWICK. [With his forefinger upraised.] Now, was this Mrs. Jones in the room alone at any time?
MARLOW. [Expressionless.] Yes, Sir.
BARTHWICK. How do you know that?
