compromised.'
'I just did it too hard. Her bones were old and brittle. The last guy I tubed was the starting center for the football team-he had a neck like my waist. She was seventy years old. I should've handled her more carefully.'
'That's probably true,' David said. 'But it was an honest mistake, the kind of mistake that happens in a hospital. I might have made it myself as a medical student.'
Carson raised his head. 'Really?'
'Yes,' David lied. Carson watched him for a moment. The room was poorly lit-the soft evening air barely filtering through a yellow curtain-and David couldn't make out his face clearly. 'UCLA is a teaching hospital,' he continued. 'There is no teaching process that doesn't progress through trial and error. We have as many checks and balances in place as we can, but we learn with our hands in the body. Being a physician is different from being an accountant, a lawyer, a mechanic. When we slip up, the cost sometimes gets paid in human life. That's what we sign on for. We're not beyond error. We're not beyond causing pain when we misstep. Or death.
'You certainly need to learn from this-you'd be a fool not to-but this was not compromised care. She was a seventy-year-old stroke victim, for Christ's sake, and you had to get her tubed quickly.'
Carson's lips trembled. 'I saw her daughter on my way out.' He lowered his eyes behind a hand, and his breathing quickened.
'And you'll see more crying family members over the course of your career. But you'll also see some who are elated because you just saved a child, a parent, a sibling.'
'Dr. Lambert told me to take some time off. He said I should-'
David glanced again at the half-packed suitcase. 'Dr. Lambert doesn't make the decisions in my division.' He stood and faced Carson's lowered head. 'You're a fine physician. With fine medical instincts. Don't make us lose a good doctor over something like this. It could have happened to anyone.'
When Carson raised his head, his eyes shone, red-rimmed and moist. Before he could respond, the doorbell rang. David took the liberty of answering it and found Diane outside, tapping a notebook against her thigh. 'Is he all right?'
'Seems to be holding up.'
'Can I see him?'
'You know what?' Carson's voice was cracked and wavering. He did not rise. 'I appreciate your both stopping by, but I could use a little time by myself right now.'
Diane leaned around David. 'If you need us,' she said. 'Page away.'
David stepped outside and pulled the door gently shut behind him. They walked down Barrington, side by side. Diane opened her notebook, a hint of excitement creeping into her voice. 'So, get this. When Clyde-or Douglas-worked at the hospital, he had a prescription for lithium carbonate. Eskalith, to be precise.'
David readjusted his stethoscope across his shoulders. 'Well, the patient in the NPI whom I just interviewed-he said that Clyde tried to steal his medication once. And guess what one of his meds is?'
'Lithium.'
'That's right. Evidently Clyde thought it would help control his emerging violent urges.'
'But its primary use isn't to control violence. It's for mania.'
'I know. But it can help against violence. It's been used to treat aggression in prison inmates and the mentally retarded. But the extent to which lithium actually controls violence isn't important. What's important is Clyde thinks it helps control violence. If he's after lithium, we have a paper trail. Who wrote the prescription?'
'Well, that's just it,' Diane said. 'Dr. Warren.'
'Dr. Warren? An orthopod prescribing lithium?'
'I know. I checked it out with him. He's never heard of Douglas Da-Vella, of course. Clyde must've gotten ahold of his DEA number somehow.'
'Well,' David said, 'Clyde must've made plenty of deliveries to Orthopedics. Horace does a lot of cutting for them. Joints and whatnot. It would have been easy enough to lift a loose prescription off a counter somewhere and copy down a DEA number.'
'Why didn't he just go see someone and get drugs prescribed legally?'
'When he came into the ER, I asked him if he was on any drugs, and he became intensely defensive. I'd guess he's ashamed of the fact he needs help. Scared to admit it outright. It's not uncommon, especially for someone presumably uneducated. So he forged a prescription.'
Diane added, 'And his meds would've all been covered by his employee health plan. Eskalith doesn't come free.'
'But he gets fired-'
'— goes off the health plan-'
'— can't afford drugs-'
'— believes that this affects him-'
'— and begins acting drastically,' David finished.
Diane whistled. 'Holy shit.'
'What are the signs of lithium toxicity, Dr. Trace?'
'Upset stomach, difficulty concentrating, clouding of consciousness, hair loss, weight gain… ' She paused. 'It's as bad as Dilantin.'
'What else?'
'Excessive thirst, metallic taste in the mouth, GI distress, acne, frequent urination.' She paused, shaking her head, a faint smile crossing her face.
'Slurring of speech, swelling of hands, psoriasis of the fingernails, nystagmus, ataxia, hypothyroidism,' David added. 'There are many more, of course, but these seem to be the relevant ones.'
'But one thing doesn't make sense,' Diane said. 'If he lost his prescription coverage when he was fired months ago, then why was he displaying signs of lithium toxicity just last week?'
'Because he's still taking it.'
'But my friend at the DEA said there have been no prescriptions of any kind filled in the past three months for either Clyde C. Slade or Douglas DaVella. So how's he getting it?'
'Maybe he's been stealing it.' David made a mental note to tell Ed about this possibility.
Just south of the post office, they turned into a park composed of two converted baseball fields. Range Rovers and Land Cruisers pulled up and dogs bounded from tailgates-dalmatians and Rhodesian Ridgebacks and Great Danes-and headed for the large lawn ahead. David had forgotten about the dog park, and found himself entertaining the idea of trading in his wife's cockatoo for a Labrador. A golden retriever nuzzled Diane's hand and she laughed, crouching to scratch behind its ears. Its owner, a young Hollywood type in a tight black Kenneth Cole T-shirt that showed off his prodigious biceps, used the opportunity to strike up a conversation with Diane, while David stood by dumbly.
When Muscles finally strode off to join the other dog owners, Diane and David headed for the field. David felt a tug at his sleeve and looked down to see a hand covered with paint, the fingernails and rough cuticles flecked white and green. It belonged to a disheveled kid in his midtwenties with a long, pointed goatee and a pair of glasses with a green thumbprint at the edge of one of the lenses. The kid wore Tevas and a ripped Berkeley T-shirt, also splattered with paint. Even the greyhound dog at his side was speckled with green dots.
'Hey, Dr. S!' the kid said amicably.
'Hello, Shane.'
'Hey, man, I'm sorry about Elisabeth. She was one of the good ones.'
'Yes. Yes she was.'
'If she hadn't come to my opening at that shithole gallery on Cahuenga, I'd still be running the coasters at Magic Mountain.'
The greyhound sped off and began furiously humping Hollywood guy's leg. David watched with perverse amusement.
'Oh, shit,' Shane said, running over to retrieve his dog. 'I'll see you around, man,' he called over his shoulder.
Diane and David hiked up in the bleachers overlooking the former baseball diamond and watched the dogs wrestle and chase objects. The brief discussion about Elisabeth, compounded by his sleep deprivation, had unsettled him. He knew Diane could see it in his face and was grateful she turned to the more pressing matters at
