I studied the card. All it had on it was Elaine Boldt's name and address and the date she'd been in. December 28. Was I on the right track? I turned the notion over in my mind.

"Marty Grice would have come in first," I said, "and then recommended Dr. Pickett to Elaine."

"That's not hard to verify," Mrs. Pickett said. "See? On the back of the card, I have that line says 'referred by' and here's Mrs. Grice's name sure enough. Actually, we do that so if folks skip out on their bill, we have some way to trace back."

"Could I see Marty's chart?" I asked.

"Well, I don't see why not."

She went back to the file cabinet and pulled a slim folder out of the drawer marked G-I and passed it to me. Marty's name was neatly typed across the tag on the top. I opened the file. There were three sheets inside. The first was a medical questionnaire, asking for information about medications, known allergies, and past illnesses. Marty had completed the form and signed it, automatically authorizing "all necessary dental services." The second was a dental history inquiring about root canals, bleeding gums, occasional bad breath, and grinding or clenching of teeth. The third sheet contained information about treatment actually rendered, with a line drawing of the top and bottom rows of teeth laid out like a Mercator projection, current fillings marked in ballpoint pen. Marty's name was neatly typed on the top line. Below were Dr. Pickett's brief handwritten notes. A routine visit. She'd had her teeth cleaned. There were apparently no dental caries. X rays had been done and she was scheduled to return in June. I stared at it for a long time, running the whole sequence of events through my head. Everything seemed to be in order except for the date: December 28. I moved over to the window and held the chart to the light. I could feel a chill smile forming because somehow I'd

Known it would come down like that. I just hadn't believed I would actually find the proof. Yet here it was. Someone had neatly whited out the name originally typed in and typed Marty's name right over it. I ran my finger across the top line, feeling for the name typed underneath as though it were done in Braille. Elaine Boldt's name was visible as a faint imprint under the name Marty Grice. The last few pieces were falling into place. I was certain hers were the charred remains recovered from the Grices' house that night. I closed my eyes. It suddenly seemed very strange. I'd been tracking Elaine for ten days without realizing I'd already seen her in a photograph in the homicide file, burned beyond recognition. Marty Grice was alive and I suspected that she and Pat Usher were one and the same. There were details to nail down yet, but I had a very good idea how the murder had been set up. "Are you feelin' all right?" "I'm fine," I said briefly. "Did you want to talk to John?"

"Not right now, but at some point, yes. You've been a big help, Mrs. Pickett. Thanks."

"Well, I don't know what I did, but you're certainly welcome." I shook her hand, dimly aware of the mystified gaze that followed me as I left. I got in my car and sat there, trying to figure out what to do next. Jesus, how had they assured that the stomach contents would match? That must have been a slick one. The autopsy report indicated the blood type was O-positive, the most common type, so that was easy enough. Marty and Elaine were close in height. It wasn't as though the murder victim was completely unknown. Everyone assumed it was Marty, and the dental X rays had simply been used to confirm her identity. There was no reason to imagine that the dead woman was anyone else. Leonard and his sister had talked to her on the phone at nine and Lily claimed Marty had hung up to go answer the door. The call to the police station was a little flourish someone thought up for the effect. Mike was right about the time. At 8:30 that night, there was a woman s body wrapped up in a rug. It just wasn't his aunt. Elaine must have been bludgeoned to death sometime earlier, with enough of her jaw and teeth left intact to make identification possible. So many things were suddenly falling into place. Wim Hoover must have recognized Marty going in or out of Elaine's apartment. Marty or Leonard apparently got to him before he got to a phone.

I started the car and pulled out of the lot, turning left. I headed over to the police station and parked out front in a fifteen-minute green zone across the street. Once inside the station, I stopped at the counter on the left. Beyond the counter, there was a doorway leading back into the squad room.

Some cop in plainclothes I'd never laid eyes on spotted me standing there as he passed the door. He paused.

"You need some help?"

"I'm looking for Lieutenant Dolan."
