"Well, he had a cold, but not a bad enough one to make him go to bed as he did. He took to his room, and Mrs. Fane attended to him herself. All day she was with him. Just before six she came out of his room, and told his man that he was asleep and was not to be disturbed. She then called me into her room, and told me that she had to go away on business. She did not want it to be known that she was out of the house, and asked me to put on one of her dresses and sit all the evening in the drawing-room till she came back." "Did she explain why she went to town?" "No. Nor did I ask. I never thought that anything was wrong. I fancied she might have gone up to see Mr. Frederick Mason, as she was always calling on him. She had quarrelled with her husband, so I thought the letter he received was about some business that was wrong----" "What business?" "The business of Mason & Son. Mr. Fane is a partner with Mr. Mason, but Mrs. Fane attends to matters. As I say, she often went to see her brother, and I thought she did so on this night unbeknown to Mr. Fane. For that reason, as I supposed, she wanted me to pretend to be her, so that neither he nor the servants would think she had been out of the house. I said Mr. Fane might want me, but she said he would not, as she had given him a sleeping-draught, and he would not awaken till the morning. Well, she paid me so well that I agreed. I put on her dress and sat in the drawing-room. She told the servants to go to bed when they liked, as she would require nothing more. So all the evening I was not disturbed, and the servants, thinking I had gone out--I made up a story for them," said Emily artfully--"never came near me. My mistress caught the six train up." "At what time did she come back?" "After midnight. She caught the last train down." "Did she seem disturbed?" "Not at all. She simply came in and said that she had done her business. Then she paid me the money and sent me to bed, after hearing that all was well, and that the other servants suspected nothing. Then she remained in the drawing-room looking over some papers." "You suspected nothing wrong?" "I did not," replied Miss Doon, with assurance. "Not until you spoke of her singing the song did I think anything wrong." "Yet you read the report at the inquest." "I did. But it never struck me that----" "I see," interrupted Bocaros, rubbing his hands. "Well, you can be quite sure, Emily, that Mrs. Fane came to Ajax Villa on that night. Can she drive a motor-car?" "Yes. She had one down at Westcliff-on-Sea." "Then it's her, without a doubt. She stole Tracey's motor-car, and leaving it in Charing Cross station-yard, went along by the underground to Liverpool Street, where she caught the last train. Jasher told me that Tracey's own idea is, that a woman did this, and that a woman killed Mrs. Brand. Ah! with your evidence we'll have her." "What will you do?"
