In the five minutes it takes James to produce coffee, Klempner mounts his murder board on the wall. I'm half-way down my cup as he finishes pinning up the information he has - limited so far. Despite the reduced information available for the latest victim, some differences are immediately visible.
James holds his breath as his eyes scrape over the central image, briefly flick over the other boards, then back again. "He mutilated her face. He'd not done that with the others."
"That's right," says Klempner. "Also, he strangled her using the hairpiece before completing the act using strands from the wig and his trademark banknotes."
My stomach roils. I gulp at my coffee, more for something to do than because I want it. "How are you feeling? Dealing with... with this?"
"It doesn't do the women any good to get emotional about it." Klempner's voice remains steady, but he doesn't make eye contact, instead pinning a newspaper cutting by the central image.
