"A cane? Did somebody have a cane?" Lucas asked, looking up at Swanson. Swanson shrugged.

"But could have been a doorjamb, or something like that," the AME continued. "Here" He picked up the woman's head, gently, as though he might have had a daughter of his own, and turned it. A small indentation marked the back of the woman's head, near the top; there was a smear of blood, enough to show the line of the injury.

"We think she might have walked in on the murder, by accident, and the killer went after her. Hit her with anything he had," Swanson said. "Maybe banged her head against the wall."

"Why would he stuff her in the closet?" Lucas objected, but the AME interrupted: "Look at this."

"What?"

He was peering closely at the woman's scalp, then reached back, felt in his bag, and took out a hand lens. "I think, uh, it looks like a little flake of paint in her hair" He looked up at Swanson. "Don't let anybody touch the doorjambs or any of the wooden trim. Anywhere she could whack her head. You might find an impact mark and maybe a hair or two." That could make the difference between murder and manslaughter, or even an accident.

"All right," Swanson said. He looked up and down the hall at all the doorjambs; there seemed to be dozens.

Lucas went back to his first thought. "Why couldn't this one have been killed first, and then"

" 'Cause Maison was strangled and she wasn't wearing any underpants, and the condition of her vulva and her pubic hair would suggest that she'd very recently been engaged in sex," Swanson said. "If somebody had killed Lansing first, we thought it was pretty unlikely that he'd stop off to bang Maison and then strangle her."
