I thought for a moment. "Nothing very much until the late afternoon, when I go down to the House," I replied. "Then to-morrow you shall see the end of this thing with me," Mr. Bundercombe promised. "If luck goes our way you will find we shall have quite a pleasant few minutes." Eve put her head in at the tent and we hastened to join her. She drew me a little on one side. "I think it's all right," I told her. "I am so glad," she replied. "And, Paul, hadn't you better drop dad a hint that Mrs. Bundercombe will be home to-morrow? I think he'd better have the shine taken off his nails!" * * * * * At twelve o'clock the next morning I met Mr. Bundercombe by appointment in the Burlington Arcade. We strolled slowly round into Bond Street. Mr. Bundercombe was, for him, unusually serious. He looked about him all the time with swift, careful glances. As we turned into Bond Street his pace became slower and slower. Within a yard or two of the spot where I had first seen him disappear he paused, and under pretense of talking earnestly to me he looked up and down and across the street with keen, careful glances. At last, with a sudden turn he led the way into the passage. Together we ascended the stairs. On a door almost opposite to us at the end of the landing was another little brass plate, on which was engraved the name of Mademoiselle Blanche. Mr. Bundercombe took a latchkey from his pocket and opened the door, which he carefully closed after him. "No one here!" I remarked. "Not yet!" Mr. Bundercombe said, a little grimly. "From now onward you will be able to understand certain things. Miss Blanche informed me that to-day she had an invitation to go into the country. It was the only way I could discover the day in which they were planning to bring off the coup. If I had been an occasional visitor she might have risked my coming and finding her away. Since, however, I presented myself every morning at eleven o'clock she was forced to tell me. You understand as much as that?" "Perfectly." "You see where we are then," Mr. Bundercombe continued. "Has any reason occurred to you for the young lady's unalterable decision that no other spot in the whole of London would do for her manicure parlor?" I looked out the window. "We are next door to Tarteran's," I observed. Mr. Bundercombe smiled approvingly. "We are within a few yards," he said, "of the jeweler's shop that contains more valuable gems than any other establishment in the world. We are at the present moment within forty yards of a million pounds' worth of jewels. When you come to reflect upon the character and the past of our friend Dagger Rodwell, you will understand the significance of that fact."
