"You're back a little early, aren't you?" I asked.

"We skipped the last three sights on the tour because the Rhode Islanders were cold and the rest of us were gettin' antsy we'd miss the bus."

I shook my head. "The point of this trip is NOT to prove how punctual you are. The point is to see Switzerland, to sample the culture, to live a little."

"Tell you the truth, Emily, Bernice's hearin' aid was hummin' so loud, I couldn't hear a thing Sonya was sayin'. Sittin' on the bus wasn't so bad. At least we got outta the rain. And Wally conducted a nice sing-along." She tilted her head and gave me a quizzical look. "I don't recall your hair lookin' like that at breakfast this mornin', dear. Your mother's been hintin' that I'm losin' my memory. Don't tell her, but I think she may be right."

"Trust me. You're fine." I looked around the lobby. There were a few New Englanders milling around the front desk, but most people had headed back to their rooms so we were pretty much alone until Bernice spotted Nana and headed in our direction. She sat down at the end of the sofa and let out an audible sigh.

"I need to catch my breath before I head upstairs," she sputtered.

"Did you enjoy the tour?" I asked.

"What?"

"I said, DID YOU ENJOY THE TOUR?"

She gave me a vacuous smile. Nana caught my eye.

"She took her hearin' aid out, dear. If you want an answer, you'd have better luck talkin' to a kumquat."

That was handy. I exchanged vacuous smiles with Bernice and returned my attention to Nana. "I have something to tell you, and you have to promise to keep it to yourself."

She made a motion of locking her lips and throwing away the key. "I promise."

"I talked to Inspector Miceli this morning, and he told me that Andy's death looks suspicious. They think he might have been murdered."

"No."

"Yes. And the killer could be your Mr. Nunzio."

"No!"

"Yes. And what's worse, if it's not Nunzio, it could be someone on the tour."

"No kiddin'."

"And if the killer thinks we overheard something in Andy's room last night, he could be after us, too!"

Nana froze up like the Tin Man in a rain shower. "That's not good."

"So Inspector Miceli said we should watch our backs, and if we see anything suspicious, we should report it. And for heaven's sake, if you should see Mr. Nunzio again, don't stop to chat. Run!"

"But he seemed like such a nice man." She looked thoughtful for a moment. "You think we should arm ourselves?"

"With what?"

She gave her finger waves a slow, pensive scratch before pointing an excited finger at me. "Defense spray."

"Like mace?"

"Like hair spray."

Hmm. That might work. A blast of aerosol to the eyes wouldn't cause irreparable damage to anyone's eyesight, but it might slow them down. Slowing down was good. "Great idea. I have some in my suitcase."
