What do we find out about Beatrice Taylor, the woman Emily Brent is accused of killing

From the text:

“Beatrice Taylor was in service with me. Not a nice girl - as I found out too late. I was very much deceived in her. She had nice manners and was very clean and willing. I was very pleased with her. Of course all that was the sheerest hypocrisy! She was a loose girl with no morals. Disgusting! It was some time before I found out that she was what they call ‘in trouble.’” She paused, her delicate nose wrinkling itself in distaste. “It was a great shock to me. Her parents were decent folk, too, who had brought her up very strictly. I’m glad to say they did not condone her behaviour.”
