Here is the sincere note of Tragedy! Surely, Oscar Wilde is among the dramatists! The action of the third act takes place in the library of Lord Goring's house. It is inspired in the very best spirit of intrigue. Lady Chiltern, mindful of Lord Goring's friendship, has, in the first bewilderment of her discovery, written a note to him,--"I want you. I trust you. I am coming to you. Gertrude." Lord Goring is about to make preparations to receive her, when his father, Lord Caversham, most inconveniently looks in to pay him a visit, the object of which is to discuss his son's matrimonial prospects. The visit, therefore, promises to be a lengthy one, and Lord Goring proposes they should adjourn to the smoking-room, advising his servant, Phipps, at the same time that he is expecting a lady to see him on particular business, and who is to be shown, on her arrival, into the drawing-room. A lady does arrive, only she is not Lady Chiltern, but Mrs Cheveley, who has not announced her advent in any way. Surprised to hear that Lord Goring is expecting a lady, and while Phipps is lighting the candles in the drawing-room, she occupies her spare moments in running through the letters on the writing-table, and comes across Lady Chiltern's note. Here, indeed, is her opportunity. She is just about to purloin it, when Phipps returns, and she slips it under a silver-cased blotting-book that is lying on the table. She is, perforce, obliged to go into the drawing-room, from which presently she emerges, and creeps stealthily towards the writing-table. But suddenly voices are heard from the smoking-room, and she is constrained to return to her hiding-place. Lord Caversham and his son re-enter and Lord Goring puts his father's cloak on for him, and with much relief sees him depart. But a shock is in store for him, for no sooner has Lord Caversham vanished, than no less a personage than Sir Robert Chiltern appears. In vain does Lord Goring try to get rid of his most unwelcome visitor. Sir Robert has come to talk over his trouble, and means to stay. Lady Chiltern must on no account be admitted. So he says to Phipps: _Lord Goring._ When that lady calls, tell her that I am not expected home this evening. Tell her that I have been suddenly called out of town. You understand? _Phipps._ The lady is in that room, my lord. You told me to show her into that room, my lord. Lord Goring realises that things are getting a little uncomfortable, and again tries to send Sir Robert away. But Sir Robert pleads for five minutes more. He is on his way to the House of Commons. "The debate on the Argentine Canal is to begin at eleven." As he makes this announcement a chair is heard to fall in the drawing-room. He suspects a listener, and, despite Lord Goring's word of honour to the contrary, determines to see for himself, and goes into the room, leaving Lord Goring in a fearful state of mind. He soon returns, however, "with a look of scorn on his face."
