I forced a laugh past my constricted throat, and gestured for Holmes to precede me to the door.

The solid dark wood was dull with neglect, the varnish lifted in narrow yellow sheets where the years of rain had blown past the protective overhang of the portico. Thick moss grew between the paving tiles; an entire fern grotto had established itself in the cracks where stonework met door frame. I heard the sound of the tumblers moving in the lock, a sound that seemed to shift my innards within me. Holmes turned the knob without result, then leant his shoulder against the time-swollen wood, taking a sudden step across the threshold as the door gave way.

The dark house lay open to us. I looked over Holmes' shoulder down the hallway, seeing little but a cavern; steeling myself, I took a step inside. As I did so, the corner of my eye registered an oddly familiar rough place in the frame of the door, about shoulder height. I stopped, one foot on either side of the threshold, and drew back to examine it.

A narrow indentation had been pressed into the surface, some four inches in height and perhaps half an inch wide. Screw-holes near the top and the bottom, and a gouge a third of the way down from the top where someone had prised the object out of the varnish that held it fast. A mezuzah, I thought, and suddenly she was there.

My mother—long rustling skirt and the graceful brim of a hat high above me—pushing open the glossy front door with one hand while her other came up to brush the intricate carved surface of the bronze object. A blessing on the house, laid at the entrance, mounted there by command and as recognition that a home is a place apart. My Jewish mother, touching it lovingly every time she entered. And not only my mother: My fingertips remembered the feel of the carving, cool arabesques protecting the tightly curled text of the blessing within.

My hand reached out of its own volition and smoothed the wood, indented, drilled, splintered, puzzling.

“What have you found?” Holmes asked.

“There used to be a mezuzah on this door. My mother's father gave it to her, the year I was born. It was his first overture after the offence of her marriage, her first indication that she might be forgiven for marrying a Gentile. And as it turned out, his last, since he died a few months later. It meant a great deal to her. And it's gone.”

“Perhaps Norbert senior took it down, for safekeeping?”

“I shouldn't think it would occur to a Gentile to remove it.”

“And your mother herself wouldn't have taken it down?”

“Not unless she didn't plan to return. And they died on a week-end trip to the Lodge—our summer house down the Peninsula. We intended to be back in a few days.”

“A friend, then, who removed it, knowing what it meant to her?”
