“The reason you can believe me is that I took the trouble to make this call. Please understand, I’m not threatening you in any way. I’m simply attempting to do business with you. Admittedly there are no guarantees. But isn’t it worth gambling, when your brother’s future is at stake?”

“You’re just some voice on the phone.”

“All right, I’m going to hang up now. I don’t need you to say yes or no, Dr. Cole. I just want you to think about the situation. If you contribute to a satisfactory outcome in this matter you’ll be rewarded. Leave it at that.”

“But I—” she began.

Uselessly. The caller was gone.

She explained it all to Bose, surprisingly calmly—or maybe not so surprisingly, given the two glasses of wine she’d poured and gulped while she was waiting for him to arrive. Her mother, who used to take a drink or two in stressful moments, had called the effect “Dutch courage.” Sandra glanced at the label on the wine bottle. Napa Valley courage.

“Bastard,” Bose said.

“Yes.”

“He must have had you followed. And he’s well connected enough that he was able to find out who you were visiting at—what’s it called?”

“Live Oaks Polycare Residential Complex.”

“Where your brother lives.”

“Kyle, yes.”

“You didn’t tell me you had a brother.”

“Well, it didn’t—I wasn’t hiding it from you.”

He gave her a speculative look. “I didn’t think you were. Did you notice anything while you were out there? An unfamiliar face, maybe a car on the road?”

“No. Nothing.”

“And nothing distinctive about the voice?”

“He sounded like he might be an older guy. A little phlegmy. Otherwise, no.” She had checked to see if her phone had recorded the caller’s number, but of course it hadn’t. “I’m not even sure why this person thinks I’m worth threatening or bribing. Congreve already bumped me from Orrin’s case. Any medical decision is out of my hands.”

“Unless they can compromise you, you’re still a dangerous loose end. You could testify about Congreve’s behavior if the matter came up in court. You could go to authorities with what you already know.”

“But without Orrin’s testimony—”

“At this point I don’t think these folks are worried about what he might say in court. I think they’re worried about what he saw in the warehouse and where that knowledge might lead a federal investigation, if he’s allowed to talk freely about it. Getting Orrin declared incompetent is just the first step. I expect they want him drugged and permanently out of sight. Or worse, dead.”

Sandra whispered, “They can’t do that.”

“Once he’s in internment,” Bose said gently, “things can happen.”
