"You have forgotten that Tatton has searched the Maze from roof to basement, Mr. Superintendent."

"Not at all. It tells nothing. There are no doubt other hidden places that he did not penetrate to in that first search. At best, it was but a superficial one."

That "first" search. Was all security slipping from Karl's feet, inch by inch?

"Believe me, you are wrong," he said; "your notion is an utterly mistaken one. I assure you on my word of honour, as truly and solemnly as I shall ever testify to any fact in this world, that Salter is not within the Maze, that he never has been. Mind you, sir, I know this. I go over occasionally to see poor Mrs. Grey in her loneliness, and am in a position to speak positively."

An unmistakable smile sat on the officer's face now. "Ay," he said, "I have heard of your occasional nocturnal visits to her, Sir Karl. The young lady is said to be very attractive."

At the first moment, Sir Karl did not detect the covert meaning. It came to him with a rush of indignation. The superintendent had rarely seen so haughty a face.

"No offence, Sir Karl. 'Twas but a joke."

"A joke I do not like, sir. I am a married man."

"Est-ce que cela empêche"--the other was beginning: for the conclusion he had drawn, on the score of Sir Karl's evening visits, was a very decided one; but Karl put a peremptory stop to the subject. He deemed the superintendent most offensively familiar and unwarrantably foolish; and he resented in his angry heart the implied aspersion on his brother's wife, the true Lady Andinnian, than whom a more modest and innocent-natured woman did not exist. And it never entered into the brain of Karl Andinnian to suspect that the same objectionable joke might have been taken up by people nearer home, even by his own wife.

The interview came to an end. Karl went away, uncertain whether he had made sufficient impression, or not, to ensure the Maze against intrusion for the future. The superintendent did not say anything decisive, one way or the other, except that the matter must be left for his consideration. It might all have been well yet, all been well, but for this new complication, this suspicion rather, touching Smith and Salter jointly! He, Karl, had given the greatest rise to this, he and no other, by stating that day that the men were cousins. He asked himself whether Heaven could be angry with him, for whatever step he took for good only seemed to lead to mischief and make affairs worse. One assurance he did carry away with him: that the young lady at the Maze might rest content: her peace personally should not be molested. But that was not saying that the house should not be.
