The view is totally killer but the house – even this main section that didn't burn – is a fucked-up mess. Drenched with water and the all-pervading acrid stench of smoke.

Jack takes some shots, notes the smoke and water damage on his tape, and then goes out into the yard. Takes some shots from this angle and doesn't see anything to change his mind that the fire started in the west wing, which must be the bedroom. He walks to the outside of the west wing, over to one of the windows, and carefully removes a shard of glass from the window frame.

First thing he notices is that it's greasy.

There's a thick, oily soot on the glass.

Jack makes this observation into the tape but what he doesn't speak into the record is what he's thinking. What he's thinking is that a residue on the inside of the glass can mean the presence of some kind of hydrocarbon fuel inside the house. Also, the glass is cracked into small, irregular patterns, which means it was fairly near the origin of the fire and that the fire built up fast and hot. He doesn't say any of this, either; all he says into the tape is strictly the physical details: "Glass shows greasy, sooty residue and small-pattern crazing. Radial fracture of glass indicates that it was broken by force of fire from inside the house."

That's all he says because that can't be argued with – the evidence is the evidence. Jack won't put his analysis or speculation on tape because if a lawsuit happens and it goes to trial, the tape will be subpoenaed, and if his voice is on there speculating on potential hydrocarbon fuel in the house, the plaintiff's lawyer will make it sound like he was prejudiced, that he was looking for evidence of arson and therefore skipped over evidence of an accidental fire.

He can just hear the lawyer: "You were focused on the possibility of arson from Moment One, weren't you, Mr. Wade?"
