I put that volume back and pulled the 1956 city directory, checking for the same three names-Ericksen, Treadwell, and Hernandez. Two of the three families were gone, which indicated death, divorce, or a simple move to another town. I noticed that after 1956, the county directory had been converted to a city directory that covered only Santa Maria and Lompoc, with no mention of Serena Station at all. I pulled the 1986 telephone book and searched again, hoping to find a trace. The Hernandez family was a wash, there being so many listed I knew I’d never track down the one I wanted. I had slightly better luck with Ericksen. I didn’t find a “J” or a “B,” but there was an “A. Ericksen” in Santa Maria, possibly Jon and Bernadette’s offspring. A family named Treadwell was living in Orcutt, and though the husband’s first name wasn’t a match, I thought there might be a connection. I wrote down both sets of phone numbers and street addresses.

At the desk, while I paid for my photocopies, I spoke to one of the librarians and explained what I needed. “Where else can I get information about Serena Station in 1953? I’ve gone through the old directories.”

He said, “You might want to look at the Index to Precinct Registers for Santa Teresa County. I believe we have ‘51 and 1954.”

“Great.”

Or not great, as it happened. We returned to the shelves and he found me the requisite volume from 1951. Again I sat down and looked up the community of Serena Station. The listings included names, addresses, occupations, and party affiliation (more Republicans than Democrats, for what that’s worth), but all the addresses listed were post office boxes, which didn’t do me any good. I flipped back to the pages devoted to Santa Maria, running a finger down page after page of residents. I gave up after ten minutes because the numbers were overwhelming, and I was hoping I’d already snagged what I needed. I gathered my notes and took the elevator to the ground floor in search of a pay phone.

I tried the Treadwells’ number first and bombed out big time. The Mrs. Treadwell who answered had never lived in Serena Station, had never known the Sullivans, and couldn’t be any help at all when it came to tracking down the former Serena Station Treadwells. She suspected I was trying to sell her something and declined any further questions.

I tried A. Ericksen and got a machine, on which I left the following message: “Hi, my name is Kinsey Millhone. I’m a private investigator from Santa Teresa and I’m wondering if you’re the same Ericksen who lived in Serena Station in 1953. I’d appreciate a call back when you get this message.” I recited my Santa Teresa phone number and repeated my name. Then I went out to my car and headed for the 101.
