WINSOR. Suspicious?

DE LEVIS. I didn't notice anything.

WINSOR. You must have been marked down and followed here.

DE LEVIS. How would they know my room?

WINSOR. Might have got it somehow. [A knock from the corridor] Come in.

TREISURE, the Butler, appears, a silent, grave man of almost supernatural conformity. DE LEVIS gives him a quick, hard look, noted and resented by WINSOR.

TREISURE. [To WINSOR] Yes, sir?

WINSOR. Who valets Mr De Levis?

TREISURE. Robert, Sir.

WINSOR. When was he up last?
