“We must go back,” I reluctantly consented. A wild idea had crossed my brain of following out my first impulse and of charging Miss Charity in her own house with the visits which had from time to time depopulated this house.
“I shall leave you to make the necessary explanations,” said he. “I am really rushed with business and should be down-town on the mayor’s affairs at this very moment.”
“I am quite ready,” said I. Then as I squeezed my way through between the corner of the cabinet and the foundation wall, I could not help asking him how he thought it possible for these old ladies to mount to the halls above from the bottom of the four-foot hole in which we now stood.
“The same way in which I now propose that you should,” he replied, lifting into view the object we had seen at one side of the passage, and which now showed itself to be a pair of folding steps. “Canny enough to discover or perhaps to open this passage, they were canny enough to provide themselves with means of getting out of it. Shall I help you?”
“In a minute,” I said. “I am so curious. How do you suppose they worked this trap from here? They did not press the spring in the molding.”
He pointed to one side of the opening, where part of the supporting mechanism was now visible.
“They worked that. It is all simple enough on this side of the trap; the puzzle is about the other. How did they manage to have all this mechanism put in without rousing any one’s attention? And why so much trouble?”
“Some time I will tell you,” I replied, putting my foot on the step. “O girls!” I exclaimed, as two screams rang out above and two agitated faces peered down upon us. “I’ve had an accident and a great adventure, but I’ve solved the mystery of the ghost. It was just one of the two poor old ladies next door. They used to come up through this trap. Where is Mrs. Packard?”
They were too speechless with wonder to answer me. I had to reach up my arms twice before either of them would lend me a helping hand. But when I was once up and Mr. Steele after me, the questions they asked came so thick and fast that I almost choked in my endeavor to answer them and to get away. Nixon appeared in the middle of it, and, congratulating myself that Mr. Steele had been able to slip away to the study while I was talking to the girls, I went over the whole story again for his benefit, after which I stopped abruptly and asked again where Mrs. Packard was.
Nixon, with a face as black as the passage from which I had just escaped, muttered some words about queer doings for respectable people, but said nothing about his mistress unless the few words he added to his final lament about the cabinet contained some allusion to her fondness for the articles it held. We could all see that they had suffered greatly from their fall. Annoyed at his manner, which was that of a man personally aggrieved, I turned to Ellen. “You have just been up-stairs,” I said. “Is Mrs. Packard still in the nursery?”
