"Of course you do know a lot more, don't you? There's a pound!"

While they were wrangling over the payment I crept down the passage again to the front door. Once I had reached it, I opened it softly and went out, closing it carefully behind me. Then I took to my heels and ran down the street in the direction I had come. Inquiring my way here and there from policemen, I eventually reached home, scaled the wall, and went across the garden to the morning-room window. This I opened, and by its help made my way into the house and upstairs. As I had expected that he would have gone to bed, my astonishment was considerable at meeting Mr. Wetherell on the landing.

"Well, what have you discovered?" he asked anxiously as I came up to him.

"Information of the greatest importance," I answered; "but one other thing first. Call up your housekeeper, and tell her you have reason to believe that one of the maids is not in the house. Warn her not to mention you in the matter, but to discharge the girl before breakfast. By the time you've done that I'll have changed my things and be ready to tell you everything."

"I'll go and rouse her at once; I'm all impatience to know what you have discovered."

He left me and passed through the green baize door to the servants' wing; while I went to my bedroom and changed my things. This done, I passed into the study, where I found a meal awaiting me. To this I did ample justice, for my long walk and the excitement of the evening had given me an unusual appetite.

Just as I was cutting myself a third slice of beef Mr. Wetherell returned, and informed me that the housekeeper was on the alert, and would receive the girl on her reappearance.

"Now tell me of your doings," said the old gentleman.

I thereupon narrated all that had occurred, and when I had finished, he said:—

"Do you believe then that my poor girl has been carried off by Nikola to this island called Pipa Lannu?"
