The question took her by surprise; she started, and the flush reappeared on her cheek. “I do not understand you,” she began; but, speedily recovering her self-possession, she exclaimed, in a low but emphatic tone, “No; how could you think of such a thing? It is the work of professional burglars and of them alone.”

I made a slight but unmistakable gesture towards the hall.

“Who is that girl?” I asked.

“Philippa? My maid,” she answered, without the slightest token of understanding, much less of sharing, the suspicion which I feared I had, perhaps, too strongly suggested by my rather pointed inquiry. “Or, rather,” she corrected, with some slight show of sarcasm, “she is what is commonly called a companion; being sufficiently well educated to read to me if I happen to be in the mood for listening, or even to play on the piano, if music is required in the house.”

The chill indifference of this answer stamped Mrs. Winchester as a woman of more elegance than feeling; but as that only made my rather disagreeable task easier, it would be ungracious in me to criticise it.

“How long has she been with you?” I pursued.

“Oh, a year; perhaps more.”

“And you know her well; her antecedents and associates?”

“Yes; I know her; all that there is to know. She is not a deep person, nor is she worthy your questions. Let us drop Philippa.”
