My eyes went straight to Camilla. Bebe’s desperate pleas to Miles in the library made it sound as if learning about the affair would kill Camilla on the spot. We didn’t need another dead body on our hands. If Camilla heard what Flynn said, it didn’t register. Quiet now, she stared absently at the blackened embers in the hearth.

In fact, no one spoke as Flynn’s eyes traveled the room. “Ahh,” he said slowly. “I see how it is. Everyone knew but me.”

Standing in the doorway, I tapped the toe of my wet boot on the floor. After talking to Ned I’d been fairly sure Flynn was our man. He and Bebe might have collaborated on the plan, but Flynn did all the heavy lifting. If he was the killer, though, why rob himself of his only escape from Tern Island? A visit to the boathouse earlier meant he could have taken off before we even knew he existed. Why stick around?

The man was entirely focused on outing Bebe and Ned. It was obvious he knew about the affair—but how? Flynn’s analysis appeared to be right; based on their reaction, everyone save maybe Camilla was already aware of Bebe’s tryst. So how had Flynn discovered it, and when?

It had been ages since that first interview in Flynn’s bedroom, but I probed my memory for a sign he’d known then. The conversation Flynn had with Ned when he got to the island suggested he had his suspicions. He’d questioned Ned’s decision to travel with Bebe, and noted his lover’s evasive response. Now, though, he was certain. Between yesterday and today something settled it.

On Flynn’s neck ropy veins rose up from the skin, bloated to bursting with fury and humiliation. This discovery was fresh, his emotions unprocessed. Someone had told him recently. Possibly within the hour.

I scanned the faces in the room. Next to her father, Jade was doing her best to hide hers. It was she who disclosed Jasper’s proposal plan to Ned. She’d told Miles, and possibly also Jasper, about seeing Ned and Bebe enter the shed. There was little for a girl Jade’s age to do in a place like this, especially during a storm. She hadn’t been texting or calling her friends, which meant that something else had occupied her time during the countless hours she’d spent in the parlor with her father’s wife’s eccentric family. And now Flynn was smoking one of her cigarettes.

I had to wonder whether Jade could even begin to comprehend the enormity of what she’d done. In a way, it was a shame Miles was leaving Bebe. When it came to the Sinclairs, Jade fit right in.

“Flynn,” Bebe said, glancing at Camilla once more. “Not now. Not like this.”

“How then, Bebe? Back in the city? At work? Does everyone there know, too? The irony is perfection, and you don’t even see it. I’m guilty,” he said. “And not just of releasing a couple of boats. But you know what, sis? So are you.”
