“Of course, my dear girl, but even I, in the knowledge of what has passed, cannot discern what the motive can be. If I could, all would be plain sailing, and we would soon recover her,” I said.
“Who is this Professor of whom you have spoken?” she asked, leaning her elbows upon the table, and gazing straight into my eyes.
“Professor Greer, the well-known chemist.”
“Greer?” echoed the girl, staring at me strangely.
“Yes, why?”
But she hesitated, as though disinclined to tell me something which was upon her mind.
“You know the Professor, eh, Harry?”
“I’ve met him once,” I replied, which was perfectly true.
“And only once?” she asked.
“Only once,” was my quick response.
“That’s curious.”
“Why?”
“Well – well, I suppose I ought not to tell you, for, of course, Harry – it’s no business of mine,” remarked the girl, “but as Mabel is now missing, no fact should be concealed, and I think you really ought to know that – ”
“That what?” I cried. “Tell me quickly, Gwen! Conceal nothing from me!”
“Well, that Mabel one morning received a note delivered by express messenger, and I asked her whom it was from. She seemed unusually flurried, and told me that it was from Professor Greer.”
“But she never knew him!” I gasped. “What day was that?”
“The day before you returned from Glasgow.”
“The same day on which she received that telegram from Italy purporting to be signed by me!”
I exclaimed. “Why didn’t you tell me this before, Gwen?”
“Mabel’s affairs have nothing to do with me. I am not interested in her correspondents, Harry,” she replied. “Surely it is not my place to carry tales to you, is it?”
“No; pardon me,” I said, hastening to excuse myself, “but in this affair the truth must be told.”
“Then why haven’t you told it to me?” asked the girl. “Why are you so carefully hiding other facts?”
“Because they are of concern only to myself – a secret which is mine, and mine alone.”
“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!’”
“You never heard her speak of the Professor before?” I inquired.
“Never, Harry; and, truth to tell, I was surprised that she should receive a letter from a man who she admitted to me was unknown to you.”
“She told you that?” I cried.
“She said that you were not acquainted with the Professor, and that you might object to him writing to her, if you knew.”
“Then she was in fear of discovery, eh?” I asked in a husky voice.
“Yes,” faltered the girl. “It – it almost seemed as though she was. But really, Harry, I – I know I’ve done wrong to tell you all this. I – I’m quite ashamed of myself. But it is because I am in such great fear that something has happened to my sister.”
“You have done quite right, Gwen,” I assured her. “The circumstances have warranted your outspokenness. Some men might perhaps misjudge their wives in such a case, but I love Mabel, and she loves me. Therefore I will believe no ill of her. She is the innocent victim of a plot, and by Heaven!” I cried fiercely, “while I live I’ll devote my whole life to its exposure, and to the just punishment of any who have dared to harm her!”
Chapter Twenty
One Traveller Returns
One fact was quite plain. It was the false Professor who had written to my wife. For aught I knew, the man whom I had followed from Edinburgh to Glasgow might have already been in London, and she might have met him by appointment.
During the morning I took the “forty-eight,” and ran over to Regent’s Park, passing slowly before both front and back of the house in Sussex Place. The blinds were up, but from the condition of the doorsteps it was plain that the place was tenantless.
From the “London Directory” I obtained the number of Lady Mellor’s, in Upper Brook Street, and called. The fat butler told me that Morgan, Miss Greer’s maid, had left with her mistress, and as far as he knew was down at Broadstairs with her. Her ladyship was at Bordighera.
I inquired if he knew anything of the other servants at Professor Greer’s.
“No, nothing,” was the man’s answer. “At least, nothing except that the Professor went abroad suddenly, and that they were all discharged and given wages in lieu of notice.”
“That Italian fellow discharged them, didn’t he?” I asked.
“Yes, sir. I never liked him. He’s gone abroad with his master, they say, and they’ve left a caretaker in charge.”
“Oh, there is someone there, eh?”
