“What I’m wondering is why I don’t see the first Planet of the Apes DVD that he bought at Walmart. The only one here is this old one.” Eve held up the box in her hand. “I also don’t see the Doritos or the Ding Dongs. They aren’t in the kitchen and the wrappers aren’t in the trash.”

“How about bananas? You’d think he’d have a bunch of those.”

Eve ignored the remark. “You don’t think it’s odd that they aren’t here?”

Duncan sighed and rose to his feet, one of his knees cracking. “He could have eaten the Doritos and Ding Dongs Wednesday night and tossed the wrappers with everything else he got rid of.”

“What about the DVD?”

“He could have given it to somebody as a gift,” Duncan said, rubbing his right knee. “Maybe there was a birthday at the office or something. You’re focusing on niggly stuff that doesn’t matter and you’re missing the big picture.”

“I’ve got a picture for you,” Nan said. Eve and Duncan turned to see Nan carrying a tiny digital camera in her gloved hand. The camera was neon pink and made for a child, who’d decorated it with stickers of flowers and butterflies. “I found this under his bed.”

Eve and Duncan went over to her.

“He’s a little old for a toy like that,” Duncan said.

“I don’t think it’s his.” Nan turned the camera, showed the screen to Eve and Duncan, and pressed an arrow-shaped button that enabled her to scroll through the images.

There was Cleve in a bathing suit on a swim dock at a lake, throwing a jubilant Troy into the water . . . Troy licking a melting ice cream cone . . . Caitlin in a bathing suit, grimacing as a wet golden retriever shook itself off next to her . . . Cleve and Troy roasting marshmallows over a campfire.

Eve didn’t need to see more. It was Caitlin’s camera. It had to be.

She looked at Duncan. “Definitive enough for you?”

“It will do for now,” he said.

She knew what he meant. The camera proved Coyle stole something from Tanya’s house, but it didn’t prove that he killed the family. But it was certainly enough to put him in a cell while they looked for more evidence.

“Can you hold up that camera for me?” Eve asked. Nan did as instructed and Eve took a picture of the camera with her phone. “Thanks. Please send me the photos from the memory card as soon as you can.”

“I’ll be glad to,” Nan said.

Eve started to go and then had another thought. “I’d also appreciate a rush on the DNA test from that urine sample collected on the hill.”

Duncan winced, and Eve knew immediately that she’d made some kind of mistake, but she didn’t know what it was.
