"Who are you?" I asked. "Do you work for the Van Burnams, and do you know who the lady was who came here last night?"
The poor woman, either startled by my sudden address or by my manner which may have been a little sharp, gave a quick bound backward, and was only deterred by the near presence of the policeman from attempting flight. As it was, she stood her ground, though the fiery flush, which made her face so noticeable, deepened till her cheeks and brow were scarlet.
"I am the scrub-woman," she protested. "I have come to open the windows and air the house,"—ignoring my last question.
"Is the family coming home?" the policeman asked.
"I don't know; I think so," was her weak reply.
"Have you the keys?" I now demanded, seeing her fumbling in her pocket.
She did not answer; a sly look displaced the anxious one she had hitherto displayed, and she turned away.
"I don't see what business it is of the neighbors," she muttered, throwing me a dissatisfied scowl over her shoulder.
"If you've got the keys, we will go in and see that things are all right," said the policeman, stopping her with a light touch.
She trembled; I saw that she trembled, and naturally became excited. Something was wrong in the Van Burnam mansion, and I was going to be present at its discovery. But her next words cut my hopes short.
