“Do you know,” she asked, “the name of the person for whom the bell rang to-day?”

He shook his head. “I am expecting a messenger with it any moment,” said he, looking towards the rear of the conservatory. “Is it any one who is here to-night?”

The gasp she gave might have been heard in the other room. Language and motion seemed both to fail her, and I thought I should have to go to her rescue. But before I could move, I heard the click of a latch at the rear of the conservatory, and saw, peering through the flowers and plants, the wicked face of the man with the receding forehead whom I had seen at madame’s, and in his arms he held THE BOX.

It was a shock which sent me further into concealment. Mr. S——, on the contrary, looked relieved. Exclaiming, “Ah, he has come!” he went to the door leading into the drawing-room, locked it, took out the key and returned to meet the stealthy, advancing figure.

The latter presented a picture of malignant joy, horrible to contemplate. The lips of his large mouth were compressed and bloodless. He came on with the quiet certainty and deadly ease of a slimy thing sure of its prey.

As I noted him I felt that not only Mr. S——‘s life but my own was not worth a moment’s purchase. But I uttered no cry and scarcely breathed. Miss Calhoun, on the contrary, gave vent to a long, shivering sigh. The man bowed as he heard it, but with looks directed solely to Mr. S——.

“I was told,” said he, “to deliver this box to you wherever and with whomsoever I should find you. In it you will find the name.

Mr. S—— gazed in haughty astonishment, first at the box and then at the man.

“This is irregular,” said he. “Why was I not made acquainted with the fact that a name was up for consideration, and why have you removed the box from its place and broken the connection which was made with so much difficulty?”

As he said this he looked up through the glass of the conservatory to a high building I could see towering at the end of the garden. It was the building in which I had first seen that box, and I now understood how this connection had been made.
