"We're trying to track down the identity of a woman who might have died in one of the Santa Teresa earthquakes. Do you have any suggestions about where we might start to look?"

"Just a moment," he said. He consulted with another of the staff, an older woman, and then crossed to his desk and sorted through a pile of pamphlets, selecting one. When he returned he had a local publication called A Field Guide to the Earthquake History of Santa Teresa. "Let's see. I can give you the dates for earthquakes that occurred in nineteen sixty-eight, nineteen fifty-two, nineteen forty-one-"

"That's a possibility," I said to Dietz.

He shook his head. "Too late. It would have been before nineteen forty if that newspaper has any bearing. What other dates do you show?"

The librarian flipped the booklet open to a chart that listed the important quakes offshore in the Santa Teresa channel. "November four, nineteen twenty-seven, there was a seven point five quake, but that was west of Point Arguello and the damage here was slight."

"No casualties?" Dietz asked.

"Evidently not. There was an earthquake in eighteen twelve that destroyed the mission at La Purisima. Several more from July to December nineteen oh-two…"

"I think we want something after that," I said.

"Well then, your best bet would probably be to start with the big quake in nineteen twenty-five."

"All right. Let's try that."

The man nodded and moved to a row of wide gray file cabinets, returning moments later with a box of microfilm. "This is April first through June thirtieth. The quake actually occurred on the twenty-ninth of June, but I don't believe you'll find a newspaper reference until the day after." He pointed to the left. "The machines are over there. Use the schematic diagram to thread the film."

"If I find something I need, can I get a copy?"

"Certainly. Simply position that portion of the page between the two red dots on the screen and press the white button in the front."

We sat down at one of four machines, placing the spool on the spindle to the left, slipping the film across the viewer and attaching it so that it would wind onto the spool on the right side of the machine. I turned the automatic-forward knob from off to me slow speed position. The first page of the paper came into view against a background of black. The edges of the pages were ragged in places, but for the most part the picture was clear. Dietz stood behind me, looking over my shoulder as I turned the knob to fast forward.

Days whipped across the screen in a blur, like a cinematic device. Now and men, I'd halt the process, checking to see how far we'd gone. April 22. May 14. June 3. I slowed the machine. Finally, June 30 crept into view. The big earthquake had occurred at 6:42 a.m. on June 29. According to the paper, the severity of the quake was such that the concrete pavement buckled and street signs were snapped as if they were threads. The reservoir broke and sent a flood of mud and water into Montebello. Gas and electric power were shut off immediately and in consequence, there was only one fire, easily contained. Many buildings downtown were badly damaged, the streetcar track was snapped, the asphalt pavement sank six inches in places. Residents slept outside that night and many cars were reported on the highway heading south. In all, there were thirteen fatalities. Both the dead and injured were listed. Sometimes ages and occupations were specified, along with home addresses if they were known. None among the dead seemed remotely related to the tale Agnes Grey had told me.

I was hand-cranking the machine by then, stopping the film at intervals so that we could scan each column. A prominent widow had been crushed to death when the walls of a hotel toppled in on her. The body of a dentist was removed from the ruins of his office building. There was no mention of anyone named Emily. "What do you think?" I said to Dietz.

He made a thumbs-down gesture. I rewound the microfilm and took it off the spindle. We returned the box of film to the main counter, consulting in low tones, trying to figure out what to try next, if anything. Dietz said, "What year was Agnes born?"

"Nineteen hundred, as nearly as we can tell… though there's some question. It might have been nineteen thirteen."

"So she would have been somewhere between twelve and twenty-five in nineteen twenty-five. If you figure her sister was in a five- or six-year age range of her, she could have been any age from six to thirty."

"We didn't see a female earthquake victim even close to that," I said.

Dietz lifted his brow. "For all we know, Emily was the family dog."
