Nick was desirous now of leaving the box into which he had intruded, even though the occupants of it were his friends; but he wished to leave it without attracting attention from the box adjoining.

He knew perfectly well that if either Lynne or Madge Babbington should chance to discover his presence so near to them, they would both realize that it was not chance that had taken him there.

They would be put on their guard again, particularly Madge, and there would be a longer interval than the one just passed before either of them would make another move to betray the secrets of the game they were playing.

Madge Babbington would be instantly on the alert if she were led to suspect that Nick Carter was so near to her at the very first interview—so the detective firmly believed—that she had had with Carleton Lynne.

After considering for a moment what was best to do, Nick turned, and managed to catch the eye of his friend, the owner of the box he was in, and he motioned for him to cross over, so that they could have a word alone together.

“Tom,� he said, in a whisper, “I want you to make my apologies to your wife and her guests, will you?�

“But you’ll stop and see them, and say hello, won’t you, after this act?� Stanton replied. “I know that Tillie will be greatly disappointed if you do not.�

“I’d like to, Tom, but you see I am here to-night on business. I found your box rather by accident, and took the liberty of dropping in to rest and to listen, as I told you; but now I must get busy again.�

“Well, later, then?�

“I’ll try to return, if I can; but I won’t promise. Now, be a good chap, and tell me that you’ll make my apologies, and I’ll slip out of the box without their knowing anything about it.�
