“What do you want me to do?” I asked.

“You stay here – who knows what he’s up to. Maybe he’s just trying to draw you out of the building.” At my mutinous look, he added, “Besides, if he calls back, you’d better be here.”

“If he stays true to form, he won’t call again today. Let me go out on it. I’m the only one reading about the mythology. Maybe I’ll see something the others would miss.”

“Forget it,” he said, and shooed us out of his office.

I drew some quick sympathetic looks from the others as they hurried off. Cassandra.

I went back to my desk and reread the story of Aeacus, more carefully this time. A plague of serpents caused the island of Aegina’s water to be poisoned. Additionally, the locals had suffered drought, famine, and a pestilent wind from the south. Aeacus awoke from his ants-to-men dream to discover it was raining, the serpents were gone, and a new populace of hard-working subjects was at his command. Talk about sweet dreams.

I thought of Thanatos’ letters, and of what he had said on the phone. Aeacus had seen his future army on an oak. But perhaps, as with many of his other references, Thanatos didn’t literally mean that I could find Rosie Thayer near an oak tree. What about the other places in Las Piernas which might be connected to oaks, or to the word “oak”?

I logged on to my computer terminal and asked for a program that serves as a guide to the city; it lists streets, public buildings, developments, parks, schools, and other points of interest in Las Piernas. Given any address, it will also display an area map. I searched under the word “oak.” A few seconds later, a list appeared on the screen. A restaurant called The Oak Room. A development called Oakridge Estates. Oak View Apartments. The Oakmont Hotel. Oakwood Elementary School. Oak Knoll Shopping Center. About twenty streets: Oak Park, Old Oak, Oak Point, Oak Meadow, Twin Oaks, Oak Grove, Sleeping Oak.

Sleeping Oak Road. That one caught my attention. Aeacus had seen the army of ants twice: on an oak, and while he was asleep.

I brought the map display up on the screen. Sleeping Oak was a long, residential street that wound its way through the hills. I debated with myself for a while, tried thinking of other ways to look at Thanatos’ messages. But the street name was the only possibility that really nagged at me.

I saw that John’s door was closed, and gathered up my coat, purse, and keys. I pulled out a copy of the photo of Rosie Thayer and tucked it into a pocket. I had almost made it to the newsroom door when a hand caught my shoulder. I turned to see Lydia.

“Where are you going?” she asked in a low voice.

“Just out to my car for a minute.”

“Then where?”

No use trying to fool her. “Listen, Lydia, I can’t sit here all day. I’ve got an idea I want to follow up on.”

“If Thanatos doesn’t kill you, John will.”

“I’ll take my chances.”

“That’s what I thought you’d say. Come over to the desk for a minute.” When she saw that I would protest, she said, “Come with me or I’ll walk right into John’s office before you can make it out of the building.”

At the City Desk, she unlocked a cabinet and handed me a cellular phone.

“You know the lecture on how much a call on one of these costs the paper,” she said, “so I won’t make you listen to it again. But take this with you and use it if you need help. That way, when I’m at your funeral, I’ll feel like I did what I could to save an old friend.”

“Aren’t you the chipper one. Okay, I’ll take it.”

“Will you tell me where you’re going?”

“Sleeping Oak Road. Thanks for the phone – and the concern.”

LAS PIERNAS SITS on a curve of the California coastline; most of its beaches face the south. As some custom-home builders have noticed over the past five years, the views from the south side of hillside streets like Sleeping Oak Road were some of the best in the inland part of the city. You could see almost all of Las Piernas below, and the ocean beyond it. The view from the north side of the street was not so picturesque, but some homeowners had overcome this handicap by trying to build taller houses than their neighbors across the street.

Many of the homes were old by Las Piernas standards, modest dwellings built in the 1920s. About every fourth or fifth house had been razed and replaced with a larger, more modern structure. I didn’t see an oak tree anywhere.

I started on the south side, and walked from house to house, knocking on doors, asking the few people who were home if they had seen the woman in the photo, or noticed any unusual activities on the street. I asked if any of their neighbors had moved in fairly recently. If they hadn’t closed the door in my face by then, I got around to asking about their neighbors’ habits. I came across people who had grudges against others on their block, and got the lowdown on who never cut their lawn, whose kids were holy terrors, whose dog barked endlessly, and which couple got drunk and played loud music in the middle of the night.

I listened to it all, knowing that neighborly snoopiness is nothing to ignore. In among all that apparently useless information, someone may have a little gem of observation that will prove to be invaluable. But I didn’t come across anyone who had seen Rosie Thayer, or who knew of a neighbor who got home late on the night she disappeared, or who had heard or seen anything that might help me find her.

As I hiked closer to the crest of the hill, I noticed that there were more empty lots near the top, staked signs promising more new construction where the view was best. As I passed each lot, I stopped to look for trampled grass or newly turned earth. Although I was looking for Rosie Thayer and believed she was probably dead, I was quite pleased not to discover anything that looked like a shallow grave.

I had almost run out of houses on that side of the street and still had the north side to check out on the way down. I was discouraged, feeling certain that my street-name hunch was a total waste of time. By now, the police had probably found Rosie Thayer, perhaps under an oak tree in a city park, or on an embankment near a big tree. I considered using the cellular phone to check in with Lydia, but remembered the cost of calls and decided to wait.

The thought of walking back down to my car made me wish I could whistle and get it to come up the hill for me. I had no sooner formed the image than I heard a sharp whistle from somewhere behind me, and turned to see a huge woman whose gray hair was wrapped in pink spongy curlers. She was calling to a white toy poodle as it bounced its way across a pair of empty lots.

“Brutus!” the woman screeched. “Brutus, you get your fluffy white butt right back here!”

Brutus paused, looked at her, then noticed me. That brought on a canine change of program. He made a yapping charge toward me, full of purpose. The purpose looked to be a bite out of my own fluffy white butt. His plans were foiled when the woman moved with amazing speed to scoop him up. She smiled and said, “I hope he didn’t scare you. He’s not as mean as he looks.”

The dog kept yapping, and I realized that he was the one which had been described to me as the neighborhood nominee for most annoying pooch.

“No,” I said, “I’m fine.” I introduced myself, and showed the photo to her.

She stared at it for what seemed like half an hour, dog barking the whole time, then handed it back and shook her head. “Sorry, I thought I remembered her, then it just came to me that this photo is in this morning’s paper.”

“I was wondering if I could ask you a few questions about the neighborhood.”

“Sure. My name’s Molly Kittridge, by the by. Be glad to talk with you,” she said, “but let’s go inside so I can get Brutus settled down. He’s busier than a bagful of bumblebees.”
