'I had an episode. I passed out in class. Nervous about the quiz. I remember you handing it out. The next thing I knew, everyone was screaming. I couldn't open my eyes, but I could hear the commotion and the cries, and I didn't know what happened. Oh God. Why did he jump? Graham a he was so amazing.'

Amazing? Was he? Harper had no idea. In fact, after three weeks of class, other than their majors and faces, she didn't know much about her students. And she wondered how Anna did; from what she'd observed, Anna didn't have a single friend in the class.

'It's his birthday next week. He was going to be twenty. I was going to bake a cake and bring it to class. You know, as a surprise.' Anna's eyes filled with pain. 'Damn, Loot. I really liked him.'

Harper wasn't sure how to respond. Apparently, Anna had planned a birthday party for a guy who didn't even notice her. She'd had a secret crush on Graham. Poor Anna. She wasn't a pretty girl; had a swollen, unhealthy look. Didn't fit in. Kept to herself. Even so, maybe Graham had liked her. Maybe they'd been close, privately.

And, if they had been, maybe Anna would know about his gun.

Harper put a hand on Anna's shoulder, comforting her. 'Anna, I need to ask you something. Just between you and me, OK?'

Anna nodded.

'It's delicate. I don't want to start rumors or damage Graham's reputation.'

'I can keep a secret.'

'You knew Graham pretty well?'

'Yes.' Her eyes darted away. 'Very well.'

'OK.' Harper hesitated. Even if Anna were exaggerating, it wouldn't hurt to ask. 'Anna.' She lowered her voice. 'Do you think Graham might have been, well, involved in something he shouldn't have?'

Anna's eyebrows lifted. 'Like what?'

Harper's shoulders were aching from the weight of the bags; she set them down. 'I came across some stuff in his book bag. Medications. A lot of money. And a gun.'

'What?' Anna's eyes widened. 'A gun? Money? What are you saying? He was doing something illegal? No. Not Graham. Graham was-' Her eyes seemed to lose focus, and her words began to slur. 'He wuzzobyootif . . .'

She stopped mid-syllable. Harper watched gravity take hold of Anna's body, saw her begin to fold. This time, Harper wasn't going to let someone fall right in front of her. Belting out, 'No!' she lunged for Anna's waist, but found herself grabbing Anna by an armpit and a breast, barely catching her before she hit the floor, asleep.

'I need help here!' Harper called, lowering Anna gently on to the tiles. Across the lobby, the group at the registration window gaped at them, useless and confused. Harper looked around for medical staff, saw the receptionist motioning to a security guard and a guy in metallic yellow and blue Spandex, carrying a bike helmet, running towards her, an orderly trailing him.

'What happened?'

Wait. Harper blinked. Dr Kendall? It took Harper a moment to recognize him in biking clothes. His thighs were stronger, more developed than she'd have imagined. His shoulders more muscled. He knelt, taking Anna's pulse. Efficient. In command.

'She passed out. I managed to break her fall. She said she's narcoleptic-'

Magically, Dr Kendall produced a stethoscope and held it against Anna's chest. Without looking up, he asked, 'You know her?'

'She's my student.'

He glanced at Harper, spoke pointedly. 'You said something that upset her?'

'Me? No a she was upset about the suicide. We were-'

The orderly interrupted. 'Should I get a gurney?'

'Yeah, Greg. Take her to the sleep unit. Make sure Wyatt finds her a bed.' Dr Kendall punched a number into his cell phone. 'Flo? Ron. Anna Winters is coming in . . . Yep, cataplectic . . . Just now, in the lobby. When she wakes up, chart the details. And make sure she's taking her meds, will you? Thanks.' He hung up and looked at Harper.

'Wait. You're Anna's doctor, too?'

'One of them. Sleep's one of my sub-specialties.'

Harper thought his eyes had changed color. Earlier, they'd been a hazel green. Now, they reflected his Spandex shirt, a light, glowing yellow.

Dr Kendall extended his hand, helping her to her feet. Maybe it was his biking outfit, but he seemed relaxed, more personal. 'You're having a hell of a day, aren't you, Harper?'

Yes, she agreed. A hell of a day.

Greg reappeared with another orderly and, together, they lifted Anna on to a gurney.

'So a what now?' Harper watched them wheel her away.

'She'll be fine.' Dr Kendall picked up his bike helmet. 'Don't worry. She'll be up soon.'

Harper felt responsible. She shouldn't have gotten Anna upset. 'Should I stay? Until she wakes up?'

'Stay?' Dr Kendall's head tilted, as if viewing her from a different angle. 'Well, that depends.'

It depended? 'On what?'

Ron Kendall's face remained solemn, but his golden eyes warmed. 'On whether you'll have coffee with me while you wait.'

What? Coffee with Dr Kendall? Was he serious? He watched her, waiting for an answer. Why would Dr Kendall want to have coffee with her? Harper wasn't sure what to do; since the war, she avoided social situations where roles weren't clearly defined. She couldn't accept; wouldn't know how to behave, what was appropriate to say. They'd already talked about Graham and about Hank and his progress. What else could they possibly talk about?

Moments later, Harper was still trying to answer that question as she sat in a booth, staring at the coffee shop menu.

The tag on the waitress's shirt said 'Chelsea'. Chelsea wore rings on every finger and long burgundy acrylic nails sprinkled with tiny rhinestones. She held a pencil with some difficulty, her grip encumbered by her manicure, as she stood beside their booth, waiting for their order.

'Have you ever eaten here?'

Harper shook her head.

'Really? Well, then, get ready: you're about to experience the world's greatest pie. Home-made.'

Pie? She'd downed bonbons for lunch and now she was topping them off with pie? Oh well, it wasn't as if she did this every day. Besides, there was fruit in the pies a fruit was good for you, right? Harper slid further into the booth, trying to get comfortable. And knocking her leather bag off the seat, into the aisle, where her tissues, baby wipes, Tylenol, water bottle a she still packed those supplies a plus keys, phone, wallet, pens, students' work a everything spilled out on to the floor.

Mortified, bending over to pick things up, she smacked her head against the edge of the table. 'Damn.'

'You OK?' Ron moved across the booth to help her.

'I'm fine.' Harper rubbed her skull. 'It's OK a I've got this.' She leaned down again; this time, her arm brushed her place setting, sending her napkin and silverware clattering to the linoleum. Lord. Could she be clumsier?

'Let me get that.' Chelsea appeared, easily scooping the wallet, phone, keys and papers into the big leather sack.

Mortified, Harper thanked her and shoved the bag safely into the corner of the booth. Then, folding her hands, sitting straight, she tried to regain her composure.

Dr Kendall studied the menu, politely overlooking Harper's altercation with gravity. He read the list aloud. 'Rhubarb, sour apple, gooseberry, blackberry . . .' He stopped to lick his lips before naming the cream pies.

Chelsea poured coffee, and Dr Kendall ordered gooseberry a la mode, Harper blackberry. Ron smiled. His teeth were perfectly aligned, sparkling white. Patrician teeth.

Harper bit her lip. This was precisely why she kept to herself. She couldn't do polite conversation, didn't have the skill anymore. Didn't think the way civilians did, didn't have the knack. She searched for a topic, but all she could think about was Dr Kendall's skintight neon Spandex. The man didn't have a trace of fat. Not anywhere. Just defined, lean muscles rolling when he moved, biceps flexing as he lifted his coffee cup. And there it was: a topic. 'So, Dr Kendall, you bike a lot?'

'Ron.'

Ron?

'Every day, weather permitting. The hills are a great workout. Cycling's my escape. I get real Zen about it, you know, into the zone. It's my only break from work.'

'You're very devoted to the Center.'

'Devoted?' Ron chuckled. 'Most people who know me a especially my ex-wives a have used other terms. Like self-absorbed, obsessive, compulsive, ambitious, uncompromising. I like "devoted".'

Ex-wives? Plural? Harper picked up her cup, unable to think of a follow-up. She sipped. Damn. She shouldn't have come.

Dr Kendall a Ron a seemed completely comfortable with the silence. Unhurried, he regarded her wordlessly, warmly.

Say something, she told herself. Anything. Ask him another question. Ask about his work. 'So, Dr a I mean, Ron a' she stumbled over his name a 'why did you become a doctor?' Actually, it was a good question; she was curious.

'No choice,' he grinned. 'I'm a third-generation physician. It's in my blood. My two brothers, sister and I are all in medicine, various specialties. My grandfather was a surgeon; so was my dad. It was never a question that we kids would follow. It got pretty intense. Like a you know that song, "The leg bone's connected to the knee bone"?' He sang it. 'We learned it this way: "The fibula's connected to the patella . . ." All the way up the body. And that was just preschool.' He smiled. 'What about you? How did you get into a sorry, remind me what you teach?'

'Archeology.'

'Right. Why?'

Harper hesitated. Over the past weeks, she and Dr Kendall had held frequent, often prolonged conversations, but he'd never expressed the slightest interest in her or her career. Even now, he was probably asking only to be polite.

'I got into it while I was in Iraq.'

'You were in Iraq?' His eyes were a startling shade of amber.

She sat straight, recited her name, rank and serial number. 'After my parents divorced, Mom couldn't afford tuition, so I did ROTC. The army sent me to college.' Why had she said that? He didn't need to know her life story.

'So what was it like? Iraq.'

Harper stiffened. Didn't want to discuss it.

'Sorry. I didn't mean to-'

'No problem.'

'You were wounded? Your leg?'

He was a doctor, had seen her limp. No need to be secretive. 'Suicide bomber.'

'I'm sorry.' Ron leaned on his elbows, watching her. His arms were tanned, almost hairless. 'So what happened that got you into Archeology?'

He seemed genuinely interested. Before she knew it, Harper was telling him about small relics she'd found in the sand. Spent bullets. Shards of broken glass and pottery. And how one day, off duty, sifting sand through her fingers, she'd had an epiphany: the sand swallowed everything. One day, it would swallow the war and those fighting it, just as it had swallowed up generation upon generation before them. It would cover their bodies, their bombed-out ruins, their possessions, the finest of their cities. The sand would take all of it, as it always had and always would. She wanted to search for its secrets. To reclaim the past that it held.

When she finished, Ron was quiet. Still watching her.

'I've bored you,' she apologized.

'Quite the contrary.' He leaned forward, eyes glowing. 'I was captivated. You become alive. You're radiant when you talk about your field.'

Harper looked down. Unsure how to respond.

'Here you go, guys.' Chelsea rescued her, delivering two generous pieces of pie.

Ice cream and whipped cream melted in thick white puddles around warm crust. Harper cut off a wedge, lifted it to her mouth. The filling was tart, the crust flaky. She closed her eyes, savoring.

When she opened them, Ron was grinning, licking a gooseberry off his lip. 'Good, huh?'

Her mouth full, Harper grinned. Yes. It was good.

Coffee with Ron was much easier than she'd expected.

He talked about his family, its tradition of competing to out-achieve each other, the summers of his youth filled with tennis matches and sailing regattas. 'But I'm boring,' he sighed. 'Let's talk about someone interesting. Tell me about Harper Jennings. Who is she, really?'

Harper blushed, swallowed pie. 'Just who you see.'

'Who I see? Then she's a beautiful, accomplished, intriguing woman.' He smiled; her neck got hot. 'Seriously. I've done all the talking. Tell me about you. Before the army.'

Oh dear. Harper told herself to relax; she could omit whatever she wanted. 'Not much to tell. I grew up outside Chicago, near the lake. One brother. Divorced parents.' There. That was enough, wasn't it?

'Did you sail, living near the lake?'

'When I was little, my dad had a boat, but . . . he left.' And the government took it, along with his antique cars, art collection and everything else of value. Even the house.

'What did your father do?'

For a moment, Harper thought he meant what crime. But, of course, he was only asking about his profession. She tried to sound casual. 'Accounting. Financial stuff.' She stopped herself. No need to elaborate. 'But he and my mom split up. And he left.' For fifteen to twenty. By now, he'd have been released, but Harper hadn't been in touch. Didn't plan to be, despite her bargains with God.

Ron swallowed coffee. 'How old were you when he left?'

'Twelve.' She fiddled with her fork. 'Overnight, we went from ostentatiously affluent to dirt poor.'

'Ouch.' Ron raised an eyebrow, probably wondering what happened to the money.

Enough. No more about her. Harper never talked about her family. Or Iraq. So why was she suddenly blabbing about both? She took a bite of pie.

Ron watched her chew.

'What?'

'Nothing.'
