"Not a one. All I know is it's not like her not to write. I tried calling four or five times. Once some woman friend of hers answered but she was real abrupt and after that, there wasn't anything at all."

"Who was the friend? Anyone you knew?"

"No, but now I don't know who she knows in Boca. It could have been anyone. I didn't make a note of the name and wouldn't know it if you said it to me right this minute."

"What about the mail she's been getting? Are her bills still coming in?"

She shrugged at that. "It looks that way to me. I haven't paid much attention. I just shipped on whatever came in. I do have a few I was about to forward if you'd like to see them." She got up and crossed to an oak secretary, opening one of the glass doors by turning the key in the lock. She took out a short stack of envelopes and sorted through them, then handed them to me. "This is the kind of thing she usually gets."

I did the same quick sorting job. Visa, MasterCard, Saks Fifth Avenue. A furrier named Jacques with an address in Boca Raton. A bill from a John Pickett, D.D.S., Inc., right around the corner on Arbol. No personal letters at all.

"Does she pay utility bills from here too?" I asked.

"I already sent those this month."

"Could she have been arrested?"

That sparked a laugh. "Oh no. Not her. She wasn't anything like that. She didn't drive a car, you know, but she wasn't the type to get so much as a jaywalking ticket."

"Accident? Illness? Drink? Drugs?" I felt like a doctor interviewing a patient for an annual physical.

Tillie's expression was skeptical. "She could be in the hospital I suppose, but surely she would have let us know. I find it very peculiar to tell you the truth. If that sister of hers hadn't come along, I might have gotten in touch with the police myself. There's just something not right."

"But there are lots of explanations for where she might be," I said. "She's an adult. Apparently she's got money and no pressing business. She really doesn't have to notify anybody of her whereabouts if she doesn't want to. She might be on a cruise. Or maybe she's taken a lover and absconded with him. Maybe she and this girl friend of hers took off on a toot. It might never occur to her that anyone was trying to get in touch."
