“Hi, Mr. Dunham.” Terrie’s voice was bright and enthusiastic, but it wasn’t overly loud or babyish. “You have two visitors. Someone who used to work with you.”

Dunham continued to look at her.

“I didn’t work with you,” Infante said, trying for Terrie’s tone, only to come across like some hale and hearty car salesman. “But Chet here did. He was in homicide. You remember him? Probably best known for catching the Bethany case. The Bethany case.”

He repeated the last three words slowly and carefully, but nothing registered. Of course. He knew it wouldn’t, but he couldn’t help himself. Dunham kept staring at pretty Terrie. His gaze was like a dog’s, affectionate and utterly dependent. If this man was the Bethany girls’ abductor, he was a monster. But even monsters aged, became frail. Even monsters died.

Infante and Willoughby began systematically opening drawers and closets, looking for anything. Looking for everything.

“He doesn’t have a lot of possessions,” Terrie said. “There’s not much point…” Her voice trailed off, as if the man sitting in the chair, the man who followed her face and voice with such determined attention, might be surprised at the news that he was dying. “But there is a photo album, which we look at together sometimes. Don’t we, Mr. Dunham?”

She reached under the ottoman and unearthed a large, cloth-covered book, a satiny white that had faded to yellow. On the cover a blue-diapered baby crowed, “It’s a boy!” When Infante opened the book, the handwriting was clearly a woman’s, a fine up-and-down cursive hand that recorded the life of one Anthony Julius Dunham from his birth (six pounds, twelve ounces) to his christening to his high school graduation. His mother, unlike some, had never lost patience with the task of jotting down her son’s every accomplishment. A certificate for completing a summer reading program, a Red Cross card noting that he had achieved “intermediate” status as a swimmer at Camp Apache. Report cards-not very impressive ones-were affixed to the pages with black triangles.

The photos made Infante wistful for his own dad. Not because there was a resemblance between Infante’s dad and the younger, more robust Stan Dunham, but because the photos captured the generic moments of family life that everyone experienced. Goofiness around the house, landmarks on vacation, squinting into the sun at ceremonies. Each was carefully labeled in that same feminine handwriting. “Stan, Tony, and me, Ocean City, 1962.” “Tony at school picnic, 1965.” “Tony’s high school graduation, 1970.” In nine short years, the son had gone from a crew-cut towhead in striped T-shirt to a long-haired, would-be hippie. Hard on a cop, Infante thought, especially one of that era, but whatever Tony wore, the parents who bracketed him beamed with pride.

The last photo-Tony in what appeared to be a gas-station uniform-was labeled “Tony’s new job, 1973.” The book ended there, although there were still several pages left. Two years before the girls disappeared. Why had this woman stopped documenting every phase of her son’s life? Did he move out in 1973? Was he there when his father brought home a girl in 1975? What had Stan Dunham told them, how had he explained the sudden appearance of a preadolescent girl?

“Kevin, check this out.”

Willoughby had pushed aside pillows that may or may not have been arranged to hide a large cardboard carton on the upper shelf in a closet. Terrie interceded, staggering a little under the weight of the box, and Infante helped her, placing a steadying hand on her shoulder. She gave him an amused look as if she were used to such ploys, making him feel old and geezerish, another guy in her care trying to cop a feel.

The box was full of the kind of detritus that students collect. Report cards, programs, school newspapers. All from the Sisters of the Little Flower, Infante noted-and featuring the name of Ruth Leibig. No album for Ruth, whoever she was, although her grades were certainly better than Tony’s. No photographs either, and nothing dated before the fall of 1975. There was a diploma, though, from 1979. Strangest of all, there was an old-fashioned tape recorder, a bright red box shaped like a purse. He pushed a button, but nothing happened, of course. The tape inside was Jethro Tull’s Aqualung . On the bottom of the player was an equally old-fashioned label, the kind made with one of those guns. “Ruth Leibig,” it said.

Infante dug deeper in the box and found something stranger still: a marriage certificate, also dated 1979. Between Ruth Leibig and Tony Dunham, as witnessed by his parents, Irene and Stan Dunham.

Tony’s dead? That, according to Nancy and Lenhardt, was the piece of information that had surprised the woman during their interview. Not saddened, however. Shocked and upset, even angered. But she hadn’t been the least bit sad. At the same time, she had never mentioned Tony, not by name.

“What happened?” Infante asked Stan Dunham, who seemed startled by the tone of his voice, the loudness of it. “Who was Ruth Leibig? Did you kidnap a young girl, kill her sister, then screw the little one until she hit her teenage years, when you made a present of her to your son? What happened on that farm, you sick old fuck?”

The nurse was appalled. She wouldn’t be kindly inclined toward him if he called her in a week or so. Remember me? I’m the detective who cursed at the old man you think is such a sweetheart. Wanna go out sometime?

“Sir, you must not speak that way-” Dunham didn’t seem to notice that anything was happening.

Infante opened the photo album, pointed to the last picture of Tony. “He’s dead, you know. Burned up in a fire. Maybe murdered. Did he know what you did? Did his girlfriend know?”

The old man shook his head, sighed, and looked out the window, as if Infante were the demented one, a raving lunatic to be ignored. Did he understand anything? Did he know anything? Were the facts locked in his brain or gone forever? Wherever they were, they were inaccessible to Infante. Stan Dunham returned to looking at his nurse, as if seeking her assurance that this disruption to his routine would end soon. When’s it going to be just you and me again? he seemed to be asking her. She spoke to him in a soft, reassuring voice, stroking his hand.

“That’s not actually allowed,” she said with a worried glance at Infante. “Touching patients like that. But he’s the nicest man, my favorite of all the ones in my care. You have no idea.”

“No,” Kevin said. “I don’t.” God knows what he’d have done to you if he’d met you when you were a teenager.

Chet Willoughby had continued to sift through the box of papers, returning to the diploma and the marriage certificate, which he studied through tortoiseshell reading glasses.

“Something’s not right, Kevin. It’s hard to be definitive, but it’s highly unlikely, based on these, that Ruth Leibig is Heather Bethany.”
