“Excellent snorkeling and diving.” Absently, Liz took down a mask to show him how to attach the snorkel. “We offer full-and half-day trips. If you’re adventurous enough, there are caves to explore.”

“And some are fairly remote,” he said idly.

“For snorkeling you’d want to stay closer to the reefs, but an experienced diver could spend days around the caves.”

“And nights.” Scott passed the snorkel through his fingers as he watched her. “I imagine a diver could go down there at night and be completely undisturbed.”

She wasn’t certain why she felt a trickle of alarm. Automatically, she glanced over his shoulder to where her police guard half dozed in the sun. Silly, she told herself with a little shrug. She’d never been one to jump at shadows. “It’s a dangerous area for night diving.”

“Some people prefer danger, especially when it’s profitable.”

Her mouth was dry, so she swallowed as she replaced the mask on the shelf. “Perhaps. I don’t.”

This time his smile wasn’t so charming or his eyes so friendly. “Don’t you?”

“I don’t know what you mean.”

“I think you do.” His hand closed over her arm. “I think you know exactly what I mean. What Jerry Sharpe skimmed off the top and dumped in that safe-deposit box in Acapulco was petty cash, Liz.” He leaned closer as his voice lowered. “There’s a lot more to be made. Didn’t he tell you?”

She had a sudden, fierce memory of a knife probing against her throat. “He didn’t tell me anything. I don’t know anything.” Before she could evade, he had her backed into a corner. “If I scream,” she managed in a steady voice, “there’ll be a crowd of people here before you can take a breath.”

“No need to scream.” He held up both hands as if to show her he meant no harm. “This is a business discussion. All I want to know is how much Jerry told you before he made the mistake of offending the wrong people.”

When she discovered she was trembling, Liz forced herself to stop. He wouldn’t intimidate her. What weapon could he hide in a pair of bathing trunks and an open shirt? She straightened her shoulders and looked him directly in the eye. “Jerry didn’t tell me anything. I said the same thing to your friend when he had the knife at my throat. It didn’t satisfy him, so he put a damaged gauge on my tanks.”
