In the closet Jack soon found a long, slim knife, and with it set to work digging out the clay and moss between two logs near the center of the back. It was slow work, as the clay was almost as hard as cement, but he stuck at it and in the course of an hour had a hole through large enough to give a clear view of the ground at the back.

“Sure thing, and forget it, too.”

“But your father.”

“Will feel exactly as I do about it,” Rex assured him, as he took his hand.
