“Let’s deal with reality, shall we? You don’t just walk into an auction house in your jeans and backpacks. You have to blend in. And that’s going to be hard.” Ian sniffed. “Considering that you’re Americans.”

“What are you talking about, dude?” Dan asked. “This is my best SpongeBob T-shirt.”

“Exactly my point,” Ian said. “An auction is a place of taste and refinement. If you barge in looking like … well, you …”

“I get your drift, Ian,” Amy said, cutting him off. “Do you know the most exclusive shop in Lucerne?”

“Of course. Here’s an idea,” Ian said. “Video your trip to the store, and I can advise you. Or else you’ll emerge looking like a mushroom, and Dan like he just rolled out of bed.”

Amy sighed. Just when she started to almost like Ian again – after all, he’d flown across the ocean and had been working around the clock to help – his snob quotient went through the roof.

She felt a sharp elbow in her ribs. Dan thrust his phone in her face. He had imported the photograph into a sketch program on his phone. He’d colored the bright blond hair brown and the eyes dark. He’d added a beauty mark above Cheyenne Wyoming’s lip.

Amy gasped. It was Vanessa Mallory!

She quickly told the others what Dan had figured out. “But why was she tailing us?” she wondered.

“Vesper One wants to keep tabs on us,” Dan said. “What else?”

“Remember, it’s in his best interest to keep you two out of jail,” Evan pointed out. “Maybe he sent her to make sure you got over the border.”

“It’s still creepy,” Amy said.

“Speaking of creepy, she probably knows where you are right now,” Evan said. “I’ve been looking at the manuals for the Vesper phone. I’m guessing that there’s a GPS embedded in it, too.”

Amy shivered as she glanced at the few pedestrians walking by. Was Cheyenne watching them right now? Was Casper?
