Zirknitz ran on thus lightly, but kept a sharp eye on his visitor, as he was anxious to know what had brought him there so early in the morning. Having fulfilled the duties of hospitality, he waited for Ellis to explain himself, which the doctor did almost immediately. "I have called, M. Zirknitz, to inquire if you can inform me of the whereabouts of Mrs. Moxton?" "Eh? How should I know? Am I my sister's keeper? Is she not in Myrtle Villa, Dukesfield?" "No, she has not been there for five days. Your sister Janet has disappeared from Pimlico also." "How do you know that, my brave doctor?" demanded Zirknitz, mockingly, yet with a shade of anxiety in his manner. "Because I called there. Mrs. Amber informed me that Mrs. Moxton had taken away Miss Gordon. She did not know whither they had gone. I thought you might have had some idea." "I fear, monsieur, I cannot assist you. I have not seen Mrs. Moxton since that day you spoke to me at Dukesfield. My sisters leave me much to myself. Why do you wish to see them?" "I have my reasons," said Ellis, stiffly. "And they are connected with that murder. _Mon cher_ Ellis, _soyez tranquil_. I do not want to penetrate your secrets. I do not know where mesdames my sisters are. If I did I should tell you most assuredly, in spite of your bad opinion of me. But I am pleased you have come." Here M. Zirknitz rose and touched an electric button. "You will hear from my landlady that I was here on the night our dear Edgar was killed." "I don't want any evidence to prove that, M. Zirknitz. I am satisfied that you are innocent." "_Bon_. But there is a doubt in your suspicious English mind which peeps out of your eye. Ah, here is Jane. Jane," addressing the smart servant, "will you be so kind as to tell Mrs. Pastor I wish to see her at once. A pretty girl, Jane," resumed Zirknitz, as she vanished. "I like pretty women and all pretty things. You think my rooms nice, eh?" "Charming. But I did not know you were so rich." "Rich! _Ma foi_, I am as poor as a mousie mouse. If you--" Before the Austrian could explain the source of his domestic magnificence his landlady entered the room. She was a formidable-looking woman, as tall as a Guardsman, with a severe face and the glance of a predatory bird. Dressed in black, with a lace cap and lace apron, she presented a wonderfully dignified and stately appearance. Anyone more unlike the scampish, airy Zirknitz it would have been impossible to conceive, yet the relaxing of her iron visage and the softening of her eagle glance showed that Mrs. Pastor was under the spell of her lodger's charm of manner. He greeted her with a sunny smile when she entered, and pointed to a chair, but Mrs. Pastor tacitly refused to be seated, and continued to stand bolt upright in the doorway.
