 him, was terrible indeed. He leant his head on his hands.

"Mercy on us!" he muttered. "Is this a civilized country when death can walk abroad like this, invisible, not to be avoided? Tell me, Mr. Vandeleur, what I must do."

"You must be guided by me," said Vandeleur, "and, believe me, there is no witchcraft in the world. I shall place a detective in your household immediately. Don't be alarmed; he will come to you in plain clothes and will simply act as a servant. Nevertheless, nothing can be done to your wife without his knowledge. As to you, Druce," he continued, turning to me, "the police are doing all they can to find this man Silva, and I ask you to help them with your big agency, and to begin at once. Leave your friend to me. Wire instantly if you hear news."

"You may rely on me," I said, and a moment later I had left the room.

As I walked rapidly down the street the thought of Madame Sara, her shop and its mysterious background, its surgical instruments, its operating-table, its induction coils, came back to me. And yet what could Madame Sara have to do with the present strange, inexplicable mystery?

The thought had scarcely crossed my mind before I heard a clatter alongside the kerb, and turning round I saw a smart open carriage, drawn by a pair of horses, standing there. I also heard my own name. I turned. Bending out of the carriage was Madame Sara.

Her eyes narrowed. The brimming tears dried as though by magic. Her glance became scornful.

"Thank you," she answered; "your reply tells me that she did not die naturally. How very appalling! But I must not keep you. Can I drive you anywhere?"

"No, thank you."

"Good-bye, then."

She made a sign to the coachman, and as the carriage rolled away turned to look back at me. Her face wore the defiant expression I had seen there more than once. Could she be connected with the affair? The thought came upon me with a violence that seemed almost conviction. Yet I had no reason for it—none.

To find Henry Joachim Silva was now my principal thought. Advertisements were widely circulated. My staff had instructions to make every possible inquiry, with large money rewards as incitements. The collateral branches of other agencies throughout Brazil were communicated with by cable, and all the Scotland Yard channels were used. Still there was no result. The newspapers took up the case; there were paragraphs in most of them with regard to the missing step brother and the mysterious death of Edith Dallas. Then someone got hold of the story of the will, and this was
