"Explanations later," said he. "For the present we want you here."
It was no easy task for me to linger there with all my doubts unsolved, waiting for the decisive moment when Mr. Gryce should say: "Come! Look! Is it she?" But the will that had already sustained me through so many trying experiences did not fail me now, and, grievous as was the ordeal, I passed steadily through it, being able to say, though not without some emotion, I own: "It is Althea Knollys! Changed almost beyond conception, but still these girls' mother!" which was a happier end to this adventure than that we had first feared, mysterious as the event was, not only to myself, but, as I could see, to the acute detective as well.
The girls had withdrawn long before this, just as Mr. Gryce had desired, and I now expected to be allowed to join them, but Mr. Gryce detained me till the grave was refilled and made decent again, when he turned and to my intense astonishment—for I had thought the matter was all over and the exoneration of this household complete—said softly and with telling emphasis in my ear:
"Our work is not done yet. They who make graves so readily in cellars must have been more or less accustomed to the work. We have still some digging to do."

"What," said I, "you still doubt?"
"I always doubt," he gravely replied. "This cellar bottom offers a wide field for speculation. Too wide, perhaps, but, then, I have a plan."
