Her mother had been dead nine days when Ruth found the door.

She had been through the house twice by then. It was a narrow house on a shaded lot at the edge of Blackshear, Georgia, the kind of house that had been added onto by hand over the decades, a room here, a back porch closed in there, until the floor plan made no sense and you could stand in the middle of it and not know which way the road was. Ruth had grown up in it and still got turned around. She had spent nine days boxing her mother’s life into cardboard, the good dishes and the bad ones, the church clothes, the drawers full of rubber bands and bread ties and thank-you notes her mother had never sent, and she had thought she’d seen all of it.

The door was behind the water heater, in the back of the utility room, and it was only because she was pulling the old heater away from the wall to see if it was worth selling that she found it at all. A plain door, painted the same dingy cream as the wall so that it disappeared into it. No knob. A keyhole, and above the keyhole, a hasp with a padlock the size of her palm.

Her mother’s keys were in a dish by the front door where they had sat for fifty years. Ruth tried them all. The fourth one turned.

The smell came first. Not rot. The opposite of rot, a hard chemical cleanness, formaldehyde and something under it, sweetish, that coated the back of her throat and stayed there. She found the pull string for the light by feel and yanked it and stood in the doorway looking at what her mother had kept.

Shelves. Floor to ceiling on three walls, and every shelf full of jars.

They were canning jars, mostly, the same Ball and Kerr jars her mother had put up tomatoes and pickled okra in every summer of Ruth’s childhood, and for one loose spinning second that was what Ruth thought she was looking at, a pantry, preserves, and then her eyes adjusted to what floated in the pale fluid and her mind stopped.

Hair. A whole jar of it, a soft brown drift of it suspended and turning slightly when her footstep shook the floor. The next jar, fingernails, dozens of them, thin curved crescents settled at the bottom like shells at a tide line. A jar of teeth. A jar of something she could not name, a soft folded thing gone gray at the edges. Jar after jar after jar, and each one labeled, her mother’s small tidy hand on a strip of masking tape, and each label a name and a date.

Carl W. 1961. Ada P. 1958. The Renfroe baby, 1963.

Ruth stood very still in the middle of the room. She was fifty-four years old and she knew these names. Some of them. Carl Wooten had run the feed store when she was a girl. Ada Puckett had taught the Sunday school class her mother helped with. The Renfroe baby had died, everyone said, of a fever, before Ruth was born, and its mother had never been right after, and here it was, a curl, in a jar on her mother’s shelf with a date on it.

Fifty years. The oldest dates went back before Ruth was born and the newest, on a jar near the door, read only two years ago, and Ruth understood with a cold that started in her scalp and ran down through her that her mother had never stopped. That the sweet churchgoing woman she had buried nine days ago had spent half a century taking pieces of people and bringing them home to this room and keeping them in the dark behind a painted door, and Ruth did not know how. Did not know when. Did not know how her mother had gotten close enough to Ada Puckett, to the Renfroe baby, to take what she took, and clean it, and cure it, and label it in that patient hand, and set it on the shelf and close the door and go make supper.

She wanted to leave. Her legs would not agree to it. She moved along the shelves instead the way you move toward a wreck on the highway, sick and slow and unable to look away, reading the names, and some she knew and most she didn’t, a whole town’s worth of people reduced to the one small piece her mother had wanted, and she thought, standing there, that she was going to get out of this room and drive to the sheriff and never sleep again.

Then she saw her own name.

It was on the bottom shelf, in the corner, in the oldest section, where the tape had gone yellow and the ink had gone brown with age. A pint jar, smaller than the others. The fluid inside had clouded over the years to the color of weak tea.

The label read Ruth. 1971.

She had been born in 1971.

She crouched. Her knees cracked in the silence. She took the jar off the shelf with both hands the way you’d lift something sleeping and she held it up to the bare bulb and turned it, and the thing inside turned with it, drifting up off the bottom, small and pale and curled.

It was a finger.

A baby’s finger. No longer than the first joint of her own, the skin gone soft and colorless with the years, and at the end of it, perfect, intact, was a fingernail no bigger than a grain of rice.

Ruth’s mouth had gone dry as paper. Without deciding to, she turned her left hand over and looked at the side of it, below the little finger, at the small smooth scar she had carried her whole life and never once questioned. A little pucker of white skin. Her mother had told her the story so many times that Ruth had never once questioned it. You were born with an extra little finger, sugar, just a soft little nub of a thing, and the doctor took it off when you were three weeks old, and you never even missed it.

She had never missed it. She had never thought about it. It was nothing, a common thing, a scrap of tissue snipped from a newborn and thrown away.

Not thrown away.

She looked at the jar in her hands, at the piece of herself her mother had taken before she could speak, before she could refuse, before she knew she was a person that things could be taken from, and she understood that she had not stumbled into her mother’s secret at all. She had always been in it. She was the oldest jar on the shelf but one. She was where it started. Her mother had looked down into the crib at her three-week-old daughter and seen not a child but a first specimen, and had taken her piece, and cleaned it, and cured it, and labeled it in that patient hand, and set it in the dark to begin the collection that would run for the next fifty years.

Ruth. 1971.

The fluid settled. The small finger drifted back down and came to rest against the glass, the fingernail turned outward, facing her, and Ruth crouched on the floor of the room in the dead center of the house she was born in and could not put the jar down.
