YAN WAS SITTING CROSS-LEGGED ON HIS JEEP WHEN I TURNED onto my street. Sliding from the hood, he flicked a wave. I returned it. His image flashed in my rearview as I plunged into my underground garage. Faded jeans. Black polo. Shades.

A decade down the road and the man still gave me that jolt. For once, Harry’s appraisal was perfect. Ryan was hot-damn good-looking.

All the way home I’d replayed our phone conversation. What was it Ryan had started to say? Tempe, I’m the happiest man on the planet. Tempe, I miss you. Tempe, I have heartburn from the sausage at lunch.

My neural factions squared off for their usual debate.

You were attacked. Ryan’s looking for excuses to keep you in his sights.

You’ve been threatened before. Your safety is no longer Ryan’s personal concern.

He wants to question Winston.

He could do that on his own.

He wants to know about Hippo’s girl.

The Rimouski skeleton is not his case.

He’s curious.

It’s an excuse.

Those were his words.

His voice said otherwise.

After parking, I checked Winston’s basement workshop. He was there. I explained what Ryan wanted. He agreed. I could tell he was curious about my bruised cheek. He could tell from my demeanor it was a bad idea to ask.

Ryan was in the outer vestibule when Winston and I arrived on the first floor. I buzzed him into the lobby.

“Nice shoes,” I said of Ryan’s red high-top sneakers.

“Thanks.” Ryan looked at Winston. “Undercover.”

Winston nodded knowingly.

I rolled my eyes.

“Dr. Brennan explained why I’m here?” Ryan.

“Yes.” Winston, solemn as a mortician.

Ryan produced the mug shots of Mulally and Babin.

Winston stared at the faces, brows furrowed, upper teeth clamping his lower lip. After a few moments, his head wagged slowly.

“I don’t know. I just don’t know.”

“Take your time,” Ryan said.

Winston refocused, then shrugged both shoulders.

“Sorry, man. It was so hectic that day. These dudes bothering Dr. Brennan?”

Ryan pocketed the pictures. “If you see them again, do let me know.” Grave.

“Absolutely.” Graver.

Ryan dug a card from his wallet and handed it to Winston. “I feel better knowing you’re here.”

The men locked gazes, acknowledging responsibility for the womenfolk.

I’d have done another eye roll, but it would have bothered my head.

Ryan held out a hand. Winston shook it then left, a soldier with a mission.

“Undercover?” I snorted. “With whom? The Disney police?”

“I like these shoes.”

“Let’s see what Harry’s doing.” I headed toward my corridor.

Whatever my sister was doing, it required her presence elsewhere. A fridge note explained that she’d left and would return later in the week.

“Maybe she got bored,” Ryan suggested.

“Then why come back?”

“Maybe something came up that needed her attention at home.”

“She’d need a passport to go to Texas.”

Ryan followed me to the guest room.

Clothes were everywhere. Scrambled in suitcases, heaped on the bed, draped on the chair back and over the open closet door. Relying on memory, I lifted sweaters from the desk and opened the top drawer.

Harry’s passport lay among my old bills and receipts.

“She’s gone somewhere in Canada,” I said. “Oh God. She’s probably cooking up another of her surprises.”

“Or maybe she figured the little side trip wasn’t worth mentioning.”

Worth mentioning. The phrase triggered a worrisome thought.

“Yesterday, I told Harry about the phone call, the e-mail, and the guy on the stairs. She was incensed. Immediately fingered the pair in Tracadie.”

“Mulally and Babin.”

“Harry didn’t know their names. You don’t suppose she’s gone to Tracadie?”

“That would be nuts.”

We looked at each other. We both knew Harry.

“Harry’s not convinced Obéline killed herself.” My brain was starting to spin possibilities. “Actually, though I’ve never said so, neither am I. Obéline seemed content when we visited her. Maybe Harry’s suspicions drove her to do some snooping on her own.”

“While there, ferret out Mulally and Babin. Ream them. Kill two birds with one stone.”

Even Harry wouldn’t do something that stupid. Or would she? I searched my mind for alternative explanations.

“Last night we also discussed Bones to Ashes.”

Ryan gave me a questioning look.

I told him about the book Harry had filched from Obéline Bastarache’s bedside table. And about Flan and Michael O’Connor’s vanity press, O’Connor House.

“Harry thinks Évangéline wrote the poems. Maybe she’s gone to Toronto to talk to Flan O’Connor.”

Another thought.

“Harry found out that the print order for Bones to Ashes was placed by a woman named Virginie LeBlanc. LeBlanc used a post office box in Bathurst. Maybe Harry’s gone to Bathurst.”

“Not the easiest place to get to.”

“Jesus, Ryan. What if she has gone to Tracadie?” Even to myself I was starting to sound a bit loony.

“Call her.”

“What if—”

Ryan placed a hand on my arm. “Call your sister’s cell phone.”

“Of course. I’m an idiot.”

I picked up the portable, punched Harry’s number, and listened to clicks as the call was routed. In my right ear, a phone rang. In my left, Buddy Holly and the Crickets chirped “That’ll Be the Day.”

Ryan and I both looked at the chair.

Grabbing Harry’s new red leather jeans, I dug through the pockets. And almost flinched when my fingers touched metal.

“She changed pants and forgot,” I said, extracting Harry’s sparkly pink cell.

“She’s fine, Tempe.”

“The last time Harry did this she wasn’t so fine.” My voice cracked. “The last time she almost got herself killed.”

“Harry’s a big girl. She’ll be OK.” Ryan opened his arms. “Come here.”

I didn’t move.

Taking my hands, Ryan reeled me in. As though by reflex, my arms went around him.

Frightening images played in my head, memories of my sister’s long-ago brush with crazies. An ice-pelted windshield. The crack of bullets.

Ryan made comforting noises. Patted my back. My cheek nestled into his chest.

Harry drugged and helpless.

Ryan stroked my hair.

A puppet dance of bodies in a darkened house.

I closed my eyes. Tried to calm my overwrought nerves.

I don’t know how long we stood there. How long it took for the pats to elongate into strokes. Grow more languid. Morph into caresses.

Other memories slowly took over. Ryan in a tiny Guatemalan posada. Ryan in my Charlotte bedroom. Ryan in the bedroom just beyond the wall.

I felt Ryan bury his nose in my hair. Inhale. Mumble words.

Slowly, imperceptibly, the moment redefined itself. Ryan’s arms tightened. Mine responded. Unconsciously, our bodies molded to each other.

I felt Ryan’s heat. The familiar curve of his chest. His hips.

I started to speak. To protest? Doubtful.

Ryan’s hands slid to my throat. My face. He lifted my chin.

I realized I was still clutching Harry’s mobile. I turned to place it on the desk.

Ryan twisted my hair in his fist, kissed me hard on the mouth. I kissed back.

Tossed the phone.

Our fingers groped for buttons and zippers.

The digits on my clock glowed 8:34. At some point I, or we, had migrated to my bed. Rolling to my back, I extended an arm.

Cold needles prickled my chest. I was alone.

The refrigerator door whooshed, then a drawer rattled.

Relieved, I grabbed a robe and hurried to the kitchen.

Ryan was fully dressed, holding a beer, staring off into space. Suddenly it struck me. He looked exhausted.

“Hey,” I said.

Ryan started at my voice. “Hey.”

Our eyes met. Ryan grinned a grin I couldn’t interpret. Sadness? Nostalgia? Postcoitus languor?

“You good?” Ryan asked, extending an arm.

“I’m good.”

“You look tense.”

“I’m worried about Harry.”

“If you want I can put out a few feelers, check airlines, trains, car rental agencies.”

“No. Not yet. I—” I what? Overreacting? Being cavalier? The anonymous call and e-mail had implied a threat to my sister as well as to me. “Harry’s just so impulsive. I never know what she’ll do.”

“Come here.”

I moved to Ryan. He hugged me.

“So,” Ryan said.

“So,” I repeated.

Awkward tension filled the kitchen. Birdie wandered in and broke it.

“Birdster!” Ryan squatted to deliver an ear scratch.

“Do you have to rush off?” I asked. To Lutetia? I meant.

“Is that a hint?”

“Not at all. If you’re hungry I can throw something together. But I understand if you have to get back…”

Ryan’s knee popped as he rose. “I’m starving.”

I made my standard bare-cupboard meal. Linguine with clam sauce and a tossed salad. As we prepared the food and ate, I told Ryan what I’d found out about Hippo’s girl. He listened, asked good questions.

“Leprosy. Like, clapper and bell, unclean, go away?”

“The bells were as much to attract charity as to warn people they were approaching the sick. By the way, it’s now called Hansen’s disease.”

“Why?”

“Mycobacterium leprae was discovered by Hansen in 1873. It was the first bacterium identified as causing disease in man.”

“Whatever the label, it’s a bad trip.”

“Leprosy actually exists in two forms, tuberculoid and lepromatous. The former is much milder, sometimes resulting in little more than depigmentation spots. Lepromatous leprosy is far more serious. Skin lesions, nodules, plaques, thickened dermis. In some cases the nasal mucosa becomes involved, resulting in chronic congestion and nosebleeds.”

“Not to mention the little buggers cause your flesh to rot.”

“That’s actually a misconception. It’s the body’s attempt to rid itself of the bacterium that causes tissue destruction, excessive regeneration, and eventually mutilation, not the bacterium itself. More salad?”

“Bring it on.”

I handed Ryan the bowl.

“I keep seeing that scene from Ben Hur.”

I raised both brows.

“Ben Hur’s mother and sister got leprosy so they had to live in a cave in a deserted quarry. The colony was fed by lowering food over the quarry rim.”

“OK.”

Ryan twirled and downed the last of his pasta. “Now that I think about it, I vaguely recall rumors of leprosy in the Maritimes. But it was always hush-hush. I think there was a leprosarium somewhere out there.”

“Yes. Sheldrake Island.”

“Nah.” Ryan’s forehead wrinkled in thought. “This was a hospital. I’m thinking New Brunswick. Campbellton? Caraquet?” Ryan swallowed, then air-jabbed his fork in sudden realization. “I’ll be damned. It was Tracadie. There was a lazaretto in Tracadie.”

“The town of Tracadie? As in Évangéline? Obéline? Bastarache?” I was so shocked I sounded like a moron. Or a teacher calling roll.

“Trendy burg.”

“No one ever heard of Tracadie. Now the place is in my face every time I turn around.” I pushed back my chair. “Let’s see what we can dig up online.”

Ryan’s eyes dropped to his plate. Sighing, he laid down his fork. I knew what was coming.

“Time to go?” I tried for cheery. Failed.

“I’m sorry, Tempe.”

I shrugged, a false smile slapped on my face.

“I’d rather stay.” Ryan’s voice was very quiet.

“Then stay,” I said.

“I wish it was that simple.”

Ryan stood, touched my cheek, and was gone.

Hearing the door, Birdie lifted his head.

“What happened tonight, Bird?”

The cat yawned.

“Probably a bad move.” I rose and gathered our plates. “But the nookie was great.”

After showering, I logged onto the Internet and Googled the terms “leprosy” and “Tracadie.”

Ryan’s memory had been dead on.
