“And it does not concern Mabel?” she demanded.
“No,” I replied hoarsely, “except that her acquaintance with the Professor has placed a new phase upon the mystery. Tell me all that happened concerning that note.”
“It came about eleven o’clock in the morning,” she said. “I saw a telegraph-boy come up the steps, and believed he had a message from you. Annie took the note and brought it here into the dining-room, where Mabel signed for it. She read it through, and I saw that it caused her a great shock of surprise. Her hands were trembling. I inquired what was the matter, but she made some evasive reply. I demanded to know whom it was from, and she replied that her correspondent’s name was Greer. ‘He ought never to have written to me,’ she added. ‘Men are sometimes most injudicious.’ Then she rose and placed the letter in the flames, watching it until it had been burned.”
“And is that all?” I demanded, astounded at the girl’s story.
“Yes, except that for some hours afterwards she seemed very upset. To me it appeared as though she had received word of some unusual occurrence. At noon she called a taxi by telephone, and went out. She did not return for luncheon, so I was alone. At three she came back, and I saw that she looked pale and distressed, while her eyes were red, as though she had been crying. But I attributed that to our ignorance of where you were. You know, Harry, how upset she is if when you are away you don’t write or wire to her every day,” added the girl.
The story held me utterly speechless. That Mabel was acquainted in secret with the Professor astounded me. But it had been the false Professor who had written to her. Possibly the fellow was already in London while I was searching for him in Glasgow, and, if so, what was more probable than that she should have met him by appointment?
Not one single instant did I doubt Mabel’s truth and love. If she had met this impostor, then she had been the victim of some cleverly-planned plot. I was incensed only against the perpetrators of that foul crime in Sussex Place, not against the sweet, soft-spoken woman who was so near my heart. Mabel was my wife, my love, my all-in-all.
Poor Gwen, watching my face intently, believed that she had acted as a sneak towards her sister, but I quickly reassured her that it was not so. Her revelations had sent my thoughts into a different channel.
“The telegram summoning her to Italy came after her return?” I asked.
“Yes, she was upset, and would eat no tea,” the girl answered. “Her conversation was all the time of you. ‘Harry is in danger,’ she said several times. ‘Something tells me that he is in the greatest danger.’ Then, when the message came, she became almost frantic in her anxiety for your welfare, saying, ‘Did I not tell you so? My husband is in peril. He is the victim of a plot!’”
