"I believe so."

"If Mrs. Hill-Mason visits at the houses of military officers, as it seems she does, then this inquisitive maid would be afforded many opportunities for gathering information. I intend to watch her," I said.

"And so will I, Mr. Jacox," replied the admiral's daughter, drawing her astrachan collar tighter about her throat.

Half an hour later we drove in the wagonette out to the shooting-party in the woods, where a merry luncheon was served in a marquee. I, however, returned to the house before the rest of the party and haunted the servants' hall. With Williams the butler I was on friendly terms, and finding him in the great hall, began to make inquiries regarding the guests' servants.

"You've got a German woman among them, haven't you?" I remarked.

"Yes, sir," was his reply. "A rather funny one she is, I fancy. She goes out alone for walks after she's dressed her mistress for dinner, and is out sometimes till quite late. What she does wandering about in the dark nobody knows. But it ain't for me to say a word, sir; she's a visitor's maid."

I held my own counsel, but resolved to watch.

Tea in the great hall, over which Lady Jocelyn presided, proved the usual irresponsible function, but when I went to my room to dress for dinner I became convinced that certain papers in my suit-case had been turned over and investigated.

That night I did not go in to dinner. I heard the gong sound, and when the company had gone in, I put on thick boots, overcoat, and cap, and passed through the back way along the old wing of the house, through the smoking-room, and out upon the drive.

Behind some holly bushes where I could see any one leave by the great paved courtyard where the servants' entrance was situated, I concealed myself and waited in patience. The night was dark and overcast. The stable chimes had rung out half-past eight, but I still remained until, about twenty minutes later, footfalls sounded, and from out the arched entrance to the courtyard came a female figure in a close-fitting hat and long dark ulster.
