The detective enters, and closes the door behind him.
WISTER. Sorry to disturb you, sir. A clerk you had here, two years and a half ago: I arrested him in, this room.
JAMES. What about him?
WISTER. I thought perhaps I might get his whereabouts from you.
[There is an awkward silence]
COKESON. [Pleasantly, coming to the rescue] We're not responsible for his movements; you know that.
JAMES. What do you want with him?
WISTER. He's failed to report himself this last four weeks.
WALTER. How d'you mean?
WISTER. Ticket-of-leave won't be up for another six months, sir.
WALTER. Has he to keep in touch with the police till then?
