“Do you know, Emily, I believe I haven’t got the very clearest recollection of the directions in uncle’s letter. Didn’t he say something about a passage?”

“He said that there was one between 13 and 14 Rosemary Street. The question is, is this Rosemary Street? We don’t know.”

“We’ll soon find out. Which are 13 and 14? It’s so dark it’s hard to tell.”

It was dark; which fact lent an additional charm to the situation. On one side were the backs of what seemed like mews; all they presented to us was a high dead wall. On the other was a row of cottages. If they were occupied all the inhabitants were in bed. There was not a light to be seen at any of the windows. Pollie began to peer at the numbers on the doors.

“This is 26.” She passed on. “And this is 25; so 13 and 14 must be this way.” We went farther along the street. “Here is 14—and here’s the passage.”

There was a passage, between two of the mean little houses. But so narrow an one that, if we had not been on the look-out for it, we should have passed it by unnoticed. Such was the darkness that we could not see six feet down it, so that it was impossible to tell where it led to, or what was at the end. I did not like the idea of venturing into it at all. I would have given almost anything to have flown down the street and sought the protection of that nice policeman. My heart was going pitter patter; I could feel it knocking against my corsets. I did not know if Pollie really was nervous, though I do not believe that it was in feminine human nature to have been anything else; but she behaved as though she wasn’t. I could not have made believe so well. She apparently did not hesitate about what was the best, and proper, and only thing to do. There was not even a tremor in her voice.

“What did uncle say—at the end there is a wall?”

“I—I think he did.”

“Then now for the wall.”

She dashed into the passage. I was afraid to do anything else—and she did not give me a chance to remonstrate—so I went after her. I am thankful to say that nothing happened to us as we went, though I seemed to see and hear all sorts of things. After we had gone what appeared to be a mile Pollie suddenly stopped.
