After all, Lord Prelice did not return to Hythe on that night, much as he desired to. In view of this new complication, which threatened the domestic peace of Lady Sophia Haken, her nephew decided to remain in London, and give all his energies towards solving the problem. He could not think that Haken had anything to do with the murder of Agstone. In the first place, he had no reason to kill the man; in the second, he did not possess any leaves of the Sacred Herb with which to make Shepworth unconscious. Certainly it was Agstone who had kindled the leaves in the bronze cup, but he must have obtained them from Mr. Haken—presuming he was the disguised lady—-since he could have obtained them in no other way. Sir Oliver had possessed a portion of the plant, but had used it in the library when he was murdered, so the old sailor could not have procured the leaves in that direction. Prelice began to wonder if Haken had got the leaves from Madame Marie Eppingrave to execute his purpose.
But then, so far as Prelice knew, his uncle was not acquainted with the Bond Street fortune-teller. And again, he was well acquainted with Dr. Horace, who admitted to possession of the leaves, and, more than this, had actually burnt the Sacred Herb in the New Bailey. Lord Prelice decided first to call upon his uncle in the city, and lay the facts discovered before him, and then to interview Dr. Horace. In these two several ways he might get at the truth. Also, somewhat later, he decided to again speak with Madame Marie, and if possible see her in the presence of Captain Jadby. When that buccaneer learned that Mona was engaged to another man, and that she had inherited the property, he might bow to fate and leave things alone. Finally, Prelice knew that he had a powerful ally in the fortune-teller. From what he had seen of her strong-willed character he guessed that she would stick at nothing to secure as her husband the man with whom she was infatuated.
Bearing all these circumstances in mind, Prelice sent a wire to Mona stating that business detained him in London, and also went to his club to write his first love letter. In this he carefully refrained from mentioning the case, and merely poured out his heart in a passionate dithyramb in honour of his goddess. Mona, for the moment, felt some disappointment when she noted the absence of information regarding Madame Marie, but later confessed that her lover was right. It would never have done for the first letter which had passed between them to be soiled by the sordid tragedy in which she had been implicated. All the same, much as she appreciated Prelice's slightly turgid prose, her heart hungered to learn of his doings relative to the case. She felt that she would not know a happy moment until the truth were made manifest. Then she could become Lady Prelice with a light heart.
The next day Prelice went into the city to see his uncle, and learned that Mr. Haken had gone to Paris for a few days. He was expected back on the morrow, as he already had been absent for some time, so all that his eager nephew could do was to possess his soul in patience. Prelice returned to his club rather disappointed, and there found a telegram waiting for him. It had been sent to his Hythe hotel, and had been repeated on to his club, since it was marked "Urgent." It proved to be from Horace, and asked Prelice to come up at once. "Be at my house at three in the afternoon. Important," said the wire.
"I wonder what this means?" Prelice asked himself uneasily, and fretted over the matter until the time came for him to go to Rutland Square.
There was no getting over the fact that the mystery of this case was telling on Prelice's strong nerves.
Nor was his uneasiness diminished when he found that Dr. Horace was not alone. With him were Captain Jadby and Madame Marie Eppingrave, both of whom appeared to be on very good terms with their host. As usual, the room was untidy with its litter of curiosities, but Prelice managed to find a seat with his back to the light. This he did so as to keep his face well in the shade, as he had a premonition that there was about to be a duel of words. Indeed, the first whispered remark of Horace hinted at a storm about to break.
"You silly ass," grumbled the doctor in his beard as he went forward to welcome his guest, "why couldn't you leave things alone as I told you to? Now all the fat is on the fire with a vengeance."
Prelice shrugged his shoulders with a carelessness which he was far from feeling, and saluted Madame Marie with a bow. Of Captain Jadby, who stood fidgeting by the window, he took no notice. The buccaneer noticed the omission, and resented it. "English manners, I suppose," sneered the half-caste pointedly.
Prelice sat down calmly, and took up the challenge. "Considering our last meeting, when you treacherously fired on my friend, you can hardly expect me to behave courteously."
