I read through the autopsy report, mentally summing up a lot of technical details. The pathologist reported no carbon granules deposited in the bronchial passages or lungs and no carbon monoxide in the blood or other tissues. It was therefore determined that she had been dead when the fire broke out. Additional lab tests had revealed no alcohol, chloroform, drugs, or poisons in the system. The cause of death was attributed to multiple skull fractures apparently caused by repeated blows with a blunt instrument. Because of the nature of the wounds, the pathologist estimated the object to be some four to five inches in width, speculating that it might have been a two-by-four wielded with great force, a baseball bat, or some kind of club, possibly metal. The murder weapon had never been found. Unless, of course, it was a big old board burned up in the fire, but there was no evidence to support that possibility.

The arson investigators didn't seem to have any doubts that the fire had been deliberately set. Lab tests showed traces of kerosene in the floorboards. Charring patterns throughout the house had borne this out. They'd seen the same blackened splash marks and the same liquid trails that I'd spotted when I went through the house earlier. They'd also used some sophisticated methods of verifying the point of origin and the course the fire had taken as it burned. Leonard Grice had been questioned about the kerosene and he said he'd been storing a quantity in the basement for use in two lamps and a cooking stove that he and Marty took on camping trips, which accounted for the intruder's having had access to a flammable liquid. It looked as if the burglar had come with a weapon in hand, but without any intention of burning the place down. The fire was apparently an afterthought, a hastily concocted plan to conceal the bludgeoning of Marty Grice. So far there was nothing to suggest that anybody knew she'd be there, so the cops were having a hard time imagining that the murder had been planned in advance.

There was no evidence that a time-delay device had been employed, which ruled out the possibility that Grice had rigged the fire before he left. Grice's nephew, Mike, had been questioned and cleared. He'd been seen by numerous impartial witnesses in a hangout called The Clockworks in downtown Santa Teresa during the critical period when experts speculated that the fire had been set. There were no other suspects and no other witnesses. Any other hard evidence including fingerprints had been destroyed by the fire. Elaine Boldt's name was on a list of persons to be interviewed and there was a note that Lieutenant Dolan had contacted her by telephone on the fifth. He'd made an appointment to see her on January 10, but she'd never appeared. According to the information I had, she'd left for Florida the night before.

One entry, appearing in the middle of a typed report, interested me considerably. According to a deputy at the police department, a call had come in at 9:06 on the night of the murder that might well have been placed by Marty Grice. The caller had been female, in a panic, and had blurted out a cry for help before the phone went dead. Since the call was placed to the police station instead of 911, the deputy had no way of getting a fix on the address from which the call had originated. She'd made a note of it, however, and when the murder came to light, she'd reported it to Dolan, who had included it in his report. He'd questioned Grice about that too. If it was Marty, why would she have called the station instead of dialing 911? Leonard had pointed out that he and Marty had a telephone answering machine with a rapid-dial function. She'd entered the telephone numbers of both the police department and the fire department. The answering machine was found, undamaged, on a table in the rear of the hallway with the numbers neatly printed on the index. It looked as if Marty had had some warning of the attack and had been able to reach the telephone, calling out at least part of a distress signal before she'd been killed. If she'd actually placed the call, it pinpointed the time of death at 9:06 or soon afterward.

For a moment, I harbored the fleeting hope that Leonard Grice might still be implicated. After all, as nearly as I could tell, the police had only Lily's word for the fact that he was still at her place at that time. I was speculating that he might have come home early, killed Marty, started the fire, and then parked around the block until the appropriate moment to arrive. If he and his sister were in cahoots, they could both simply maintain afterward that he'd been with her. I was out of luck on that one. Three interviews down, there was a short paragraph detailing a conversation that Dolan had had with some of Lily's neighbors who'd stopped by unexpectedly at nine P.M. to drop off a birthday present. The husband and wife both reported independently that Leonard was there and hadn't left for home until approximately ten. The time was noted because they'd been trying to persuade him to stay for a television program that came on at ten. It turned out to be a rerun and since he was anxious to get home to his wife anyway, he'd left.
