For the Sake of Elena

the direction of Parker’s Piece and the Cambridge Police Station. A turn to the right and she would head towards Newnham Road and, if she persisted far enough, to Barton beyond it. Or, he now saw, she could proceed straight ahead, crossing the street, ducking through this second gate, and continuing south along the river. Whoever killed her, he realised, must have not only known her route but also known her options. Whoever killed her, he realised, had known in advance that the only certain chance of catching her was at Crusoe’s Island.

He was feeling the cold beginning to seep through his clothes and he headed back the way he had come, maintaining a slower pace this time, one designed merely to keep himself warm. As he made the final turn from Senate House Passage where Senate House itself and the outer walls of Gonville and Caius College were acting like a refrigerated wind tunnel, he saw Sergeant Havers emerging from the gate-house of St. Stephen’s, looking dwarfed by its turrets and its heraldic carving of yales supporting the founder’s coat of arms.

She gave his appearance a poker-faced scrutiny. “Going undercover, Inspector?”

He joined her. “Don’t I blend in with the environment?”

“You’re a regular bit of camoufl age.”

“Your sincerity overwhelms me.” He explained what he had been doing, ignoring the cocked and leery eyebrow which she raised at his references to Sarah Gordon’s corroborative vomit, and finishing with, “I’d say Elena ran the course in about five minutes, Havers. But if she was intent on having a fairly long workout, then she may have paced herself. So ten at the extreme.”

Havers nodded. She squinted down the lane in the direction of King’s College, saying, “If the porter really saw her leave round six-fi f-teen-”

“And I think we can depend upon that.”

“-then she got to the island far in advance of Sarah Gordon. Wouldn’t you say?”

“Unless she stopped off somewhere en route.”

“Where?”

“Adam Jenn said his digs are by Little St. Mary’s. That’s less than a block from part of Elena’s run.”

“Are you saying she stopped off for a morning cuppa?”

“Perhaps. Perhaps not. But if Adam was looking for her yesterday morning, he wouldn’t have had much trouble finding her, would he?”

They crossed over to Ivy Court, wound their way through the ubiquitous rows of bicycles, and headed towards O staircase. “I need a shower,” Lynley said.

“As long as I don’t have to scrub your back.”

When he returned from the shower, he found her at his desk, perusing the notes he had written on the previous night. She’d made herself at home, scattering her belongings across the room, one scarf on the bed, another draped across the armchair, her coat on the floor. Her shoulder bag gaped upon the desk top, spilling out pencils, chequebook, a plastic comb with missing teeth, and an orange lapel button printed with the message Chicken Little Was Right. Somewhere in this wing of the building, she’d managed to find a stocked gyp room, for she’d made a pot of tea, some of which she was pouring into a gold-rimmed cup.

“I see you’ve brought out the best china,” he said, towelling off his hair.

She tapped her finger against it. The sound snapped sharply rather than sang. “Plastic,” she said. “Can your lips endure the insult?”

“They’ll soldier through.”

“Good.” She poured a cup for him. “There was milk as well, but there were white globs floating in it so I left its future to science.” She dropped in two sugar cubes, stirred the brew with one of her pencils, and handed him the cup. “And would you please put on a shirt, Inspector? You’ve got lovely pectorals, but I tend to go light-headed at the sight of a man’s chest.”

He obliged her by completing the dressing which he’d begun in the icy bathroom down the corridor. He took his tea to the armchair where he saw to his shoes.

“What do you have?” he asked her.

She pushed his notebook to one side and swivelled the desk chair so that she was facing him. She rested her right ankle on her left knee, which gave him his first glimpse of her socks. They were red.

“We’ve got fibres,” she said, “on both armpits of her track jacket. Cotton, polyester, and rayon.”

“They could have come from something in her cupboard.”

“Right. Yes. They’re checking for a match.”

“So we’re wide open there.”

“No. Not exactly.” He saw she was holding back a satisfied smile. “The fibres were black.”

“Ah.”

“Yes. My guess is that he dragged her by the armpits onto the island and left the fi bres that way.”

He swam by that hook of potential culpability. “What about the weapon? Have they made any headway with what was used to beat her?”

“They keep coming up with the same description. It’s smooth, it’s heavy, and it left no trace deposit on the body. The only change in what we knew before is that they’ve moved off calling it your standard blunt object. They’ve deleted the adjectives, but they’re looking like the dickens for some others. Sheehan was talking about bringing in help to have a go with the body because apparently his two pathologists have a history of being incapable of coming to a clear conclusion-not to mention an agreement-on anything.”

“He indicated there might be trouble with forensic,” Lynley said. He thought about the weapon, pondered the location, and said, “Wood seems possible, doesn’t it, Havers?”

As usual, she was with him. “An oar, you mean? A paddle?”

“That would be my guess.”

“Then we’d have trace evidence. A splinter, a speck of varnish. Something left behind.”

“But they’ve absolutely nothing?”

“Not a sprat.”

“That’s hell.”

“Right. We’re nowhere with trace evidence if we’re hoping to build a case out of that. But there’s good news otherwise. Lovely news, in fact.” She brought forth several folded sheets of paper from her shoulder bag. “Sheehan fielded the autopsy results while I was there.

We may not have trace, but we’ve got ourselves a motive.”

“You’ve been saying that ever since we met Lennart Thorsson.”

“But this is better than being turned in for sexual harassment, sir. This is the real thing. Turn him in for this and he’s had it for good.”

“Turn him in for what?”

She handed him the report. “Elena Weaver was pregnant.”

“Which naturally brings up the question of those unused birth control pills, doesn’t it?” Havers continued.

Lynley fetched his spectacles from his jacket pocket, returned to the chair, and read the report. She’d been eight weeks pregnant. It was now the fourteenth of November. Eight weeks took them back to sometime during the third week of September, before Cambridge was in session. But, he wondered, was it also before Elena herself had come to the city?

Havers was saying, “And once I told him about them, Sheehan waxed anachronistically eloquent on the subject for a good ten minutes.”

Lynley roused himself. “What?”

“The pregnancy, sir.”

“What about it?”

She dropped her shoulders in disgust. “Haven’t you been listening?”

“I was wondering about the time line. Was she in London when she became pregnant? Was she in Cambridge?” He dismissed the questions momentarily. “What was Sheehan’s point?”
