I held out my hand. "Are you Benedict?"

"Yes ma'am," he said, shaking hands with me. "You're Miss Millhone, I take it. Nice to meet you. We appreciate this." His grip was firm, but brief. He nodded toward the door to Tillie's apartment, which stood ajar. "You can go on in if you want. Officer Redfern is with her, taking down particulars."

I thanked him and moved into the apartment, glancing to my right. The living room looked like something left in the path of a tornado. I stopped and stared for a moment. Vandalism in a place like this? I moved into the kitchen. Tillie was sitting at the table with her hands tucked between her knees, the freckles standing out on her pale face like red pepper flakes. A uniformed policewoman, maybe forty years old, was seated at the table taking notes. She had short-cropped blond hair and a birthmark like a patch of rose petals on one cheek. Her name tag identified her as Isabelle Redfern and she talked to Tillie in low, earnest tones like someone trying to persuade a flier not to leap off a bridge.

When Tillie caught sight of me, tears spilled out of her and she beean to shake, as though my appearance were tacit permission to fall apart. I knelt down beside her, taking her hands. "Hey, it's okay," I said, "what's going on?"

She tried to speak, but nothing came out at first except a wheezing sound like someone stepping on a rubber duck. Finally, she managed to choke out a response. "Someone broke in. I woke up and saw this woman standing in the door to my room. My God, I thought my heart would stop. I couldn't even move I was so terrified. And then… and then, she started… it was like this hissing sound and she ran in the living room and started tearing everything up…" Tillie put a handkerchief over her mouth and nose, closing her eyes. Officer Redfern and I exchanged a look. Bizarre stuff. I put my arm around Tillie's shoulders, giving her a little shake.

"Come on, Tillie," I said, "it's over now and you're safe."

"I was so scared. I was so scared. I thought she was going to kill me. She was like a maniac, like a totally crazy person, panting and hissing and crashing around. I slammed the bedroom door shut and locked it and then dialed 911. Next thing I knew it got quiet, but I didn't open up the door until the police got here."

"That's great. You did great. Look, I know you were scared, but you did it just right and now it's okay."

The policewoman leaned forward. "Did you get a good look at this woman?"

Tillie shook her head, beginning to shake again.

This time the policewoman took Tillie's hands. "Take a couple of deep breaths. Just relax. It's over now and everything's fine. Breathe deeply. Come on. Do you have any tranquilizers on hand or alcohol of some kind?"

I got up and moved over to the kitchen cabinets, opening doors at random, but there didn't seem to be any liquor at all. I found a bottle of vanilla extract and poured the contents into a jelly glass. Tillie downed it without even looking.

She began to breathe deeply, calming herself. "I never saw her before in my life," she said in somewhat more ordered tones. "She was crazy. A lunatic. I don't even know how she got in." She paused. The air smelled like cookies.

The policewoman looked up from her notes. "Mrs. Ahlberg, there was no sign of forced entry. It had to be someone who had a key. Have you given a key to anyone in the past? Maybe someone who was house-sitting? Someone who watered your plants when you were away?"

At first Tillie shook her head and then she stopped and shot a look at me, her eyes filled with sudden alarm.

"Elaine. She's the only one who ever had one." She turned to the policewoman. "My neighbor in the apartment right above me. I gave her a key last fall when I took a little trip to San Diego."

I took over then, filling in the rest; Elaine's apparent disappearance and her sister's hiring me.

Officer Redfern got up. "Hold on. I want Benedict to hear this."

It was 3:30 in the morning by the time Redfern and Benedict were finished, and Tillie was exhausted. They asked her to come down to the station later that morning to sign a statement and in the meantime, I said I'd stay with her until she had herself under control again.

When the cops finally left, Tillie and I sat and stared at each other wearily.

"Could it have been Elaine?" I asked.

"I don't know," she said. "I don't think so, but it was dark and I wasn't thinking straight."

"What about her sister? Did you ever meet Beverly Danziger? Or a woman named Pat Usher?"

Tillie shook her head mutely. Her face was still as pale as a dinner plate and there were dark circles under her eyes. She anchored her hands between her knees again, tension humming through her like a wind across guitar strings.
