"We stay outside the rotten frame," Dutch told the boy. "I don't care what's under there. A good find isn't worth a broken neck."
They started by cutting grapevine away from the far side of the structure. The vines had braided themselves around the posts, some as thick as Callie's wrist, and their roots were anchored beneath layers of fallen boards. Callie used pruning shears while Dutch worked the stubborn stems loose with a hooked blade. Eli carried the debris clear of the suspected depression and stacked it beyond the fence.
The work went slowly. At midmorning they stopped because the ruined roof shifted as a large vine came free, and Dutch insisted on bracing the remaining upright before anyone moved closer. Eli fetched two lengths of sound timber from the barn, and Callie helped secure them without putting weight against the rotten corner. The delay irritated her, but she remembered how often her father had said that hurrying a dangerous repair merely transferred the work to a hospital.
Once the outer vines were gone, they could see what Eli meant. The soil behind the crib dropped by a shallow step along one straight edge, then rose again just before the fence. Near the center lay a band of reddish stone that did not match the gravel in the pasture. Callie knelt to clear dirt from it and discovered mortar between two stones.
"That's built," Dutch said behind her. His voice had lost its complaint. He pressed his boot into sound ground beyond the edge and crouched beside her. "You can see where somebody fitted the blocks instead of dumping them."
Eli gave Callie the smallest possible smile. It was the expression of a boy trying not to celebrate until there was something definite to celebrate. She wanted to smile back, but the brickwork had made her more cautious. If there was a buried room beneath them, there might also be unstable walls and stale air, and none of them knew how much weight the roof could bear.
They worked along the outer boundary rather than standing on top of it. After an hour, the crowbar struck iron beneath a tangle of rotted siding and compacted earth. Dutch cleared the dirt around a rusty strap hinge, and Callie found the faint vertical joint of a low wooden door set into a stone-lined recess. The opening was barely high enough for a grown person to pass through without bending.
"Well," Dutch said after a long silence, "I take back approximately half the unkind things I have said about this pile of lumber."
The door resisted their first attempt. Its lower edge had swollen into the threshold, and the iron straps were furred with rust, but careful pressure against the soundest part of the frame finally freed it. Callie stepped aside as a cloud of dry dust rolled from the opening. The smell came with it: old cedar, dried corn husks, cold earth, and the unmistakable mineral odor of a room that had been closed far longer than anybody remembered.
