Karen fidgeted with her glasses, adjusting and readjusting them on her face. “Ozzie’s parents, right? The mother, she came several times. Stayed over in the beginning, then came once or twice a week after that.”

“What about the rest of the family?”

“I have no memory of them. A shame, too. Parents seem to feel they’ll traumatize their other children by bringing them to an acute-care unit, when really, it’s good for all the children to see one another and reaffirm that each is doing okay.”

D.D.’s eyes narrowed. “And Tika’s family?”

Karen shook her head, bewildered. “Greg?” she asked.

He’d just returned with a tray bearing four cups of water. He handed me one, then Karen, then offered one to Sergeant Warren, who passed.

“Tika?” he repeated. “Little girl, ’bout a year ago? Cutter?”

“That’s the one,” Warren assured him. “I understand you worked with her.”

He nodded. “Cute little thing. Had a wicked sense of humor if you could get her to open up. But yeah, she had some self-esteem issues, depression, anxiety. Maybe even suffered sexual abuse, though she never disclosed.”

“What was her family like?” Sergeant Warren wanted to know.

“Never visited.”

“Never?”

“Never. Tika’s file described the mother as ‘disengaged.’ We never experienced anything different.”

“And our records show them living in Mattapan,” I spoke up, remembering the exchange between Sergeant Warren and the George Clooney detective. “We wouldn’t know they’d moved; our involvement was over and done.”

“Not so hard to look up,” Sergeant Warren said with a shrug.

“But why? We’re caretakers. We don’t hurt children. We help them.”

“Tell that to Lucy.”

“Fuck you!” I exploded.

“Eighteen minutes,” the sergeant shot back. “Gym Coach here just fetched four cups of water in a fraction of that time. Explain eighteen minutes.”

“Easy,” Karen interjected, ever the manager. “Let’s just take a deep breath here.”

“Lucy wouldn’t just wander into a radiology room,” I insisted hotly. “And where would she find the rope?”

“Like you said, someone must have helped her.”

“Lucy didn’t trust anyone. Had limited social skills, limited speech skills. Hell, we don’t even know that she had the dexterity required to tie knots. Whatever happened, it was done to her, not by her.”

“By someone she trusted,” the sergeant reiterated, staring at me, then the little string ball I held in my left hand.

“I wasn’t gone that long!”

“Maybe hanging a troubled kid is quick work.”

“Sergeant!” Karen protested.

As I heard myself say: “Dammit, I loved Lucy.”

“She attacked you.”

“It was nothing personal—”

“Looks like she tried to wring your neck.”

“It’s part of the job!”

“Does the rest of the staff have any bruises?”

“You don’t know what it’s like here. We’re the last line of defense these kids have. If we can’t help them, nobody can.”
