“If it isn’t,” I said emphatically, “I shall be certain he was not a real person. And if so, there must be some legend about this path which we must set to work to disinter.”

My heart beat rather faster than usual as we approached the place in the wall whence the unknown man seemed to come out, and for a few minutes our search was unsuccessful. No door was to be seen. The growth of ivy was very thick just there. I stood back a little at last, and surveyed the wall from a short distance, and at one spot it seemed to me that there was a slight break in the line. I kept my eye as closely as possible fixed on this spot while I approached it, and pushed gently against the ivy with my hand.

Yes, I had not been mistaken; but I got a start as I suddenly felt what seemed a bit of the wall itself yielding to my touch. I started back with a little exclamation which brought Isabel to my side.

“What is it?” she exclaimed. “Have you found it?”

“I have found something,” I said, and on examining more closely, it proved to be the suspected door, overgrown with ivy indeed, practically indistinguishable from the outside, but in good order nevertheless, moving on its hinges smoothly and noiselessly.

It opened inwards of course, and, strange to say, it was open, as has been shown.

“I wonder if he forgot to lock it,” I said, “or if it is always left unfastened.”

I pushed it farther ajar as I spoke, Isabel pressing forward eagerly.

“Now,” I said triumphantly, “we shall get a peep inside the enchanted ground. This is a ‘find’ of mine. Confess, Zella, that I have done more in a few days towards unearthing the mystery than you in twice as many years.”
