Lucy said, “Whoever Scarpetta six-twelve is would have had to be physically within range of John Jay’s wireless network to join it. For example, the person would have to be there using one of the college’s computers—which isn’t likely at almost midnight, when the buildings were locked, and that’s when the last e-mail was sent, right before midnight on December twenty-eighth. Or the person could have brought his or her own laptop or something smaller such as a BlackBerry, an iPhone, a PDA, some device that’s capable of logging on to the Internet. And that’s what I’m thinking—that this individual had something like a PDA and just stood on the sidewalk in front of one of the buildings and hijacked the wireless network. I’m assuming the cops found Terri’s cell phone? Or a BlackBerry or PDA if she had one? The photograph Scarpetta six-twelve sent? It could have been sent by a BlackBerry, a PDA, something like that, as I’ve mentioned.”

“Her cell phone’s being gone through.” It was Marino. “No other phones, BlackBerries, or devices you could use for the Internet. Assuming the inventory we got here is correct. Just the one phone. Plain vanilla flip phone. Was on the kitchen counter, plugged in, recharging. That and the earpiece. Also recharging.”

All of them continued to discuss and speculate, and then there was a brief lapse as Marino and Berger contacted the e-mail provider for Scarpetta six-twelve.

They got the information Lucy needed.

“The password’s stiffone, all one word.” Berger spelled it for Lucy over the phone. “Marino, maybe you could get with John Jay’s security to find out if they noticed anyone in front of the classroom building late on the night of December twenty-eighth, and again yesterday, mid-afternoon?”

“In both instances, the twenty-eighth and last night,” Benton said, “the building would have been closed due to the hour and the holiday.”

“Are there security cameras?” Berger asked.

Lucy said, “You know what I’m thinking. I’m thinking the IP’s deliberate to make it look like the e-mails are really from Aunt Kay. She’s connected with John Jay, so why wouldn’t she be sending e-mails from their wireless network? Point is, whoever’s stolen Aunt Kay’s identity by sending these e-mails doesn’t care if the IP was traced, and likely hoped or even assumed it would be. Otherwise, this person would have used an anonymous proxy—a program on a remote server that grabs files for you and disguises your real address. Or some other type of anonymizer that gives you a temporary address every time you send an e-mail, so people can’t find your real IP.”

“That’s my big battle.” Berger made her favorite complaint about the Internet.

It was one Lucy liked to hear. The devil Berger fought was one Lucy knew.
