"Where did Mrs. Harrison come from? Who was she?"
"I think she answered the mistress's advertisement."
"How long has she been here?" I asked.
"Just over a year. Mrs. Jardine didn't get on well with the last two companions she had. They were younger women, and the place was too dull for them. They wanted to go out more, and Mrs. Jardine wanted someone who was content to live the kind of life she did. So she got this elderly companion."
"Mrs. Harrison had friends, I suppose?"
"I never saw nor heard of any."
"But she received letters?"
"I can't call to mind that she ever did. I fancy she was one of the lonely sort."
She was also uninteresting and commonplace in appearance, according to Martha Wakeling's description. The word-picture I managed to draw up for circulation had nothing distinctive about it. Nor did Martha know much of her mistress's relations. Mrs. Jardine had not been on friendly terms with them, and had not seen any of them in her time, as far as she knew; the only one she had heard mentioned was a nephew, a Mr. Thomas Jardine, who lived somewhere in London.
The upper floor of the house was unfurnished and locked up, and an unfastened window on the ground floor, opening into the garden, suggested the way Mrs. Harrison had left. I took immediate steps to delay the publication of the news of the tragedy. There were points in the case which might modify first suspicions considerably, and a few hours of unhampered investigation might be of great value.
