“Or bring in a second killer,” Lynley finished. “Is that what you're thinking?”
It was, Hanken told him. Perhaps the other killer was waiting in the car. Perhaps he—or she—set out to Nine Sisters Henge in the company of the other. In any case, when it became clear that there were two able-bodied victims to dispose of instead of just one and only a single knife with which to do the job, the second killer was called into action. And the second weapon—a chunk of limestone—was used.
Lynley went back for another look at the pictures and the site plan. He said, “But why are you marking the girl as the main victim? Why not the boy?”
“Because of this.” Hanken handed over the single sheet of paper that he'd held back from the anonymous letters in anticipation of Lynley's question. Again it was a photocopy. Again it was taken from another note. This one, however, had been scrawled by hand. THIS BITCH HAS HAD IT snaked across the page, the penultimate word underlined three times.
“Was this found with the others?” Lynley asked.
“It was on her body,” Hanken said. “Tucked into one of her pockets nice and neat.”
“But why leave the letters after the murders were done? And why leave the note?”
“To send someone a message. That's the usual purpose of notes.”
“I'll accept that for a note on her body. But what about the cut-and-paste letters? Why would someone have left them behind?”
“Consider the condition of the crime scene. There was rubbish everywhere. And I dare say it was dark when the killers struck.” Hanken paused to crush out his cigarette. “They wouldn't even have known the letters were there in all the mess. They made a mistake.”
At the other end of the room, the computer finally came to life. One of the WPCs said, “About time, that,” and began inputting data and waiting for responses. The other constable did likewise, working with the activity sheets and reports that the investigative team had already turned in.
Hanken continued. “Think about the killer's state of mind, the principal killer, that is. He tracks our girl to the stone circle, all set to do the job, only to find her with a companion. He's got to bring in help, which throws him off his stride. The girl manages to run off, which throws him off further. Then the boy puts up a hell of a fight, and the camping site is turned into a shambles. All he's worried about—this is the killer, not our boy—is dispatching the two victims. When the plan doesn't go smoothly, the last thing on his mind is whether the Maiden girl brought his letters with her.”
“Why did she?” Like his superior, Nkata had gone back to look at the crime scene photos. He turned from them now as he spoke. “To show the boy?”
“There's nothing to indicate that she knew the boy before they died together,” Hanken said. “The girl's dad saw the boy's body, but he couldn't put a name to him. Had never seen him, he said. And he knows her friends.”
“Could the boy have killed her?” Lynley asked. “And then inadvertently become a victim himself afterwards?”
“Not unless my pathologist had the times of death wrong. He puts them dying within an hour of each other. How likely is it that two completely unrelated killings would occur in a single location on a Tuesday night in September?”
“Yet that's what appears to have happened, isn't it?” Lynley said. He went on to ask where Nicola Maiden's car had been in relation to the stone circle. Had plaster impressions of tyre prints been taken from that location? What about footprints in the circle itself? And the boy's face … What did Hanken make of the burns?
Hanken fielded the questions, using the map and the reports that his men had compiled thus far in the case. From the other end of the room, WPC Peggy Hammer—whose countenance had always reminded Hanken of a shovel with freckles—called out, “Pete, we've got it. Here's the DVLA.” She copied something from her terminal's monitor at the far end of the room.
“The Triumph?” Hanken said.
“Right. Got it.” She handed over a slip of paper.
