“No; I think not. The conspirators removed his furniture in order to prevent undue inquiries as to the Doctor’s disappearance. The emptying of the house may have been one to make it appear to the police that the Doctor had suddenly removed—perhaps to avoid his creditors.”

Rolfe shook his head. His opinion hardly coincided with that of the British diplomat. Besides, Max Barclay’s story of having seen a man there closely resembling him wanted explanation. With what motive had an unknown man represented him on the night in question?

“Maud Petrovitch has never written to you?” asked Harrison.

“Not a line.”

The Minister pursed his lips.

“Well,” he said, “I’m perfectly sure if she’s been in Belgrade she would certainly have come to see us. My wife used to have frequent letters from her in London.”

“I have not told Lady Harrison the reason of my inquiry—or any of the facts,” Rolfe said. “I thought I would leave it to you to tell her if you think proper. Up to the present, the Doctor’s disappearance has been kept secret between my friend Max Barclay, who was the Doctor’s most intimate chum in London, and myself.”

“At present I shall not tell my wife,” declared the diplomat. He was a man of secrets, and knew how to keep one. “Who is Max Barclay?” asked the Minister, after a pause. Rolfe explained, but said nothing regarding his engagement to his sister Marion. To it all Sir Charles listened attentively, without comment.

At last, after a long silence, he said:

“Well, look here, Rolfe. A sudden thought has occurred to me. I think it possible that to-morrow, in a certain quarter, I shall be able to make a confidential inquiry regarding the whereabouts of the Doctor. All that you’ve told me interests me exceedingly, because I have all along believed that very shortly Petrovitch was returning to power and join forces with Pashitch.”
