According to the brief police narrative, the fire started on a Sunday evening and was fully involved by the time the fire department got there. Hart was so badly burned, he could be identified only by striking similarities of tooth root and trabecular alveolar bone points in antemortem and postmortem radiographs. The origin of fire was a bathroom on the first floor, and no electrical arcing, no accelerants were detected.

ATF had been involved in the case upon invitation by the Baltimore fire department. I found it interesting that Teun McGovern had been called in from Philadelphia to lend her expertise, and that after weeks of painstaking sifting through debris and interviewing witnesses and conducting examinations at ATF’s Rockville labs, the evidence suggested the fire was incendiary, and the death, therefore, a homicide. But neither could be proven, and fire modeling could not begin to account for how such a fast-burning fire could have started in a tiny tile bathroom that had nothing in it but a porcelain sink and toilet, a window shade, and a tub enclosed in a plastic curtain.

The fire before that, in October, happened in Venice Beach, California, again at night, in an oceanfront house within ten blocks of the legendary Muscle Beach gym. Marlene Farber was a twenty-three-year-old actress whose career consisted mainly of small parts on soap operas and sitcoms, with most of her income generated from television commercials. The details of the fire that burned her cedar shake house to the ground were just as sketchy and inexplicable as those of Austin Hart’s.

When I read that the fire was believed to have started in the master bathroom of her spacious dwelling, adrenaline kicked in. The victim was so badly burned, she was reduced to white, calcinated fragments, and a comparison of antemortem and postmortem X rays of her remains was made to a routine chest film taken two years before. She was identified, basically, by a rib. No accelerants were detected, nor was there any explanation of what in the bathroom could have ignited a blaze that had shot up eight feet to set fire to the second floor. A toilet, tub, sink, and countertop with cosmetics, of course, were not enough. Nor, according to the National Weather Service satellite, had lightning struck within a hundred miles of her address during the past forty-eight hours.

I was mulling over this with a glass of pinot noir when Marino called me at almost one A.M.

“You awake?” he asked.

“Does it matter?”

I had to smile, for he always asked that when he called at impolite hours.

“Sparkes owned four Mac tens with silencers that he supposedly bought for around sixteen hundred dollars apiece. He had a claymore mine he bought for eleven hundred, and a MP40 sub. And get this, ninety empty grenades.”

“I’m listening,” I said.
