"I don't know. When I came to myself Janet was bending over me, and I was so frightened that I could explain nothing. After that I picked up the knife which was lying by Edgar's body and flung it over some bushes against the fence. Then Janet hurried me away, and told me she would take my place and deny everything. I was so dazed that I did not know what I was doing. I ran down to the cab-rank and told a cabman to drive me to Pimlico. He did so, and I recovered myself sufficiently in the cab to pay him, and to slip into the house with the latchkey which Janet had pushed into my hand. I knew that she still had our old room, so I ran up to it without seeing anyone, and locked myself in." "Mrs. Amber told me that you isolated yourself for weeks." "I did so by Janet's advice, lest Mrs. Amber should recognise me. Janet came to see me a few days afterwards, and told me about the inquest." "Did you call at Geneva Square?" asked Ellis, turning to Miss Gordon. "That is strange, for Mrs. Amber particularly explained that until a few days ago no one called save Schwartz." "I paid a visit one night when Mrs. Amber was at the theatre," explained Janet, "and I bribed Sarah, the servant--a most venal creature--to say nothing about it. It was necessary that I should tell Laura what had taken place, and hear her story. Now you know, doctor, why I fenced with you and refused to tell the truth. I was afraid lest my sister should be brought into the matter." "But Mrs. Moxton is innocent, and you knew it," protested Ellis. "Yes, I am innocent," wailed Mrs. Moxton, "but what could I do in the face of all I have told you. I cannot hold my tongue like Janet, or foresee things as she does. In one way or another I should have betrayed myself and perhaps have been arrested. Janet was right, Janet was wise to advise me to stay at Pimlico. I feigned ill-health, and would not let Mrs. Amber into my room lest she should get to know too much. Only Sarah knew me, as I had to confide in her to get food. But she held her tongue." "She nearly betrayed you though, Mrs. Moxton, by taking those cuffs to Mrs. Amber." "That was a mistake," said the widow. "In touching Edgar's body I got blood on my cuffs, and threw them aside in the bedroom. I never thought of hiding them, and Sarah took them downstairs without consulting me." "How did you manage to keep up the concealment of your identity to the end?" "I managed that," said Janet, in her firm, clear voice. "I called when I knew that Mrs. Amber was absent, and told Laura that, on account of Busham, I intended to take her away. When Mrs. Amber came back, of course, she thought that I had been in my bedroom all the time, and that Laura had called for me. She was so deceived," added Janet, smiling, "that she told me how ill I looked after lying so long in bed. But I am afraid I did look ill, with all the worry."
