I’m fine. Especially investigate Michael’s gambling debts. I think that’s the key to everything. I have a new ally on the ship. I’ll keep in touch when I can. —Robert.

Then I went to the casino—not to gamble, but to observe. I wanted to understand how desperate someone could become, what kind of debt could swallow a man, what kind of panic could make murder feel like an option. I watched men and women place large bets with the nonchalance of someone buying a magazine. I saw the thrill on faces when they won, the despair when they lost, and the way some gamblers spiraled—betting more and more in a desperate attempt to claw back what they’d thrown away. And I understood. Michael wasn’t just ungrateful. He was desperate—likely drowning in debt—and he saw his father’s death as the only way out. That night at dinner, I ran into Carl again. This time he approached my table without waiting for an invitation. “Robert,” he said, sitting across from me, “I’ve been thinking about our conversation. I need to tell you something: you don’t look like a man on vacation. You look like a man running from something… or planning something.” I stayed silent a moment, deciding how much I could reveal. “Carl,” I finally said, “have you ever discovered someone you love deeply betrayed you in the worst possible way?” His eyes softened, and I saw a flicker of recognition. “Yes,” he said simply. “My business partner. I discovered he’d been stealing from our company for years, almost drove us into bankruptcy.” “What did you do?” “What I had to do,” Carl said. “I gathered evidence, confronted him, and made sure he paid for what he’d done.” He paused, his gaze steady. “But Robert… we’re talking about your son.” I took a deep breath. Carl had shown he could hold difficult secrets, and I needed an ally—someone I could trust during these seven crucial days. “Carl,” I said, looking him directly in the eyes, “my son is trying to kill me. And I have seven days to stop him and prove what he’s planning.” Carl’s expression changed instantly. Not surprise. Not disbelief. Just the look of a man who’d lived long enough to know families can hide the darkest things. “Tell me everything,” he whispered. “From the beginning.” For the next forty minutes, I told him. The cruise gift. The phone call I overheard. The debts I suspected. The policy payout and the house money he expected after my death. Carl listened without interrupting once. When I finished, he sat quiet for a few minutes, processing. “This is very serious,” he said at last. “You’re in real danger. But it also seems to me you already have a plan.” “I’m starting to,” I admitted. “I hired a private investigator to dig into Michael’s finances, but I need more than that. I need proof no judge can ignore. I need witnesses.” “And how do you plan to get all that while you’re on this ship?” he asked. “That’s where I need your help,” I said. “Michael will try to communicate with me during the trip. He’ll call, text, pretend to be the concerned son. Every conversation is an opportunity for him to expose himself.” Carl nodded slowly. “You want to record.” “Exactly. But I can’t do it alone. I need a witness—someone with no emotional ties to Michael, someone credible.” “Count on me,” Carl said without hesitation. Then his face darkened. “But there’s something else. If Michael’s planning to stage an accident on this ship, it’s possible someone else is involved—someone on board working with him.” The thought sent ice through my veins. “You think Michael could have bribed someone from the crew?” “It’s possible. Or hired someone to pose as a passenger. You need to be very alert. Don’t trust anyone except me. Don’t accept drinks from strangers. Don’t be alone in isolated places—especially on your balcony.” I’d already thought about the balcony. Too private. Too convenient. Carl leaned forward. “I have a proposal. Spend the nights in my cabin. I have a suite with a sofa bed. That way, if someone comes looking for you in your room, they won’t find you—and we’ll be together.” His generosity moved me more than I wanted to admit. “Carl, I can’t ask you—” “Robert,” he cut in firmly, “I’m 62. I raised four children and buried a wife. I ran my own company for thirty years. I’m not afraid of a spoiled brat who wants to kill his father for money.” Then he smiled—mischievous, almost boyish. “Besides, it’s been a long time since I’ve had an exciting adventure.” That night, after dinner, Carl helped me move essentials to his cabin. It was larger than mine, with a living room separate from the bedroom and a wider balcony. But most importantly, it had two beds—two places to keep watch. As we organized my things, Carl asked detailed questions about Michael: his personality, his habits, his relationship with Clare. “Was Michael always like this,” he asked, “or is it new?” “He was always clever,” I said carefully. “Even as a little kid, he knew exactly what to say to get what he wanted. I thought it was normal childhood cunning. I never imagined it could turn into this.” “And Clare?” “At first they seemed very in love,” I said. “But lately I’ve noticed tension. Clare complains about money constantly—bigger house, expensive vacations, a better car. Michael always promises it’ll get better, he’ll bring in more.” Carl’s jaw tightened. “Now we know where that money was supposed to come from.” Around ten that night, my phone rang. Michael. Carl and I looked at each other. The moment had come. “Remember,” Carl whispered, setting his own phone to record. “Make him talk. Make him betray himself.” I answered with a voice I made soft. “Hello, son.” “Hi, Dad. How’s the cruise? Are you having fun?” His tone was perfect—caring, concerned. If I hadn’t heard that phone call with Clare, I would’ve believed him. “It’s beautiful,” I said. “The ship is amazing. My cabin is very comfortable. Thank you for this generous gift.” “You’re welcome, Dad. You deserve it. Have you met new people? Are you making friends?” The question landed wrong. Why did it matter if I was making friends? “Yes,” I said. “I met a very kind gentleman, Carl. We’re eating together.” There was an almost imperceptible pause. “That’s good, Dad. It’s important you’re not alone. But also be careful. On these cruises, sometimes there are people who take advantage of older passengers.” Carl’s eyes widened. Michael was trying to poison me against any ally. “Don’t worry,” I said. “I’m cautious. But tell me—how are things there? How’s Clare?” “Everything’s fine. Clare sends you a hug. She hopes you’re having fun and relaxing completely.” “How kind of her,” I said, letting irony hang inside my chest like smoke. Then I pushed. “Michael, can I ask you something?” “Of course, Dad. Anything.” “Why did you decide to give me this trip now? It was so sudden.” A longer pause. “Clare and I have been talking about you. We realized you seem tired—stressed—and we thought you needed a break. A real break. Get away from everything for a while.” “Get away from everything,” I repeated, glancing at Carl as he wrote every word. “Sometimes we need to disconnect from routine, don’t we?” “I suppose so,” I said. Then, like a hesitant old man, I baited the hook. “Michael, I have a silly question. Do you have a copy of my return ticket? Because I checked my documents and only found a one-way ticket.” The silence that followed was so deep it felt physical. “Michael? Are you there?” “Yes—yes, Dad. Sorry. Clare was telling me something about the tickets.” His voice was controlled, but I could hear the crack underneath. “Don’t worry. The travel agency has everything organized. You just enjoy the trip. We’ll take care of the details.” “But I want to be sure I can come back,” I pressed. “Could you check tomorrow and confirm?” “Dad, please trust me. Everything is perfectly organized. You have nothing to worry about. Just relax and enjoy.” “Okay,” I said softly. “I trust you completely.” “Perfect, Dad. I love you very much. Sweet dreams.” “I love you too,” I answered, and the lie tasted like metal. “Good night.” When I hung up, Carl and I sat in silence, processing. “That was revealing,” Carl said at last. “The way he avoided the return ticket question—the way he kept you in false security.” “And the question about making friends,” I added. “He was evaluating if I had allies. If someone would notice if something happened.” “Exactly,” Carl said. “Tomorrow we go to passenger services and verify your return status ourselves. I want to see, with my own eyes, what Michael really booked.” The next morning, we woke early with a mission. We ate breakfast in Carl’s cabin to avoid exposing me unnecessarily in public, then went to passenger services on the third floor. The office was elegant, staffed by uniformed employees behind polished desks. We approached a young woman whose badge read 

Patricia

. She greeted us with a professional smile. “Good morning, gentlemen. How can I help you?” “I need to verify my complete travel itinerary,” I said, keeping my voice calm. “My name is Robert Sullivan, cabin 847.” Patricia typed quickly and frowned. “Mr. Sullivan, I see the seven-day Caribbean cruise booked, but…” She paused, staring at the screen with confusion. “But what?” Carl asked, hearing the hesitation. “It’s a bit strange,” she said. “I see you have a one-way ticket, but no reservation appears for the return flight to Chicago. Normally our packages include complete roundtrip transportation.” Even knowing the truth, hearing it officially hurt like a punch. “What does that mean exactly?” Carl asked, pretending confusion. “It means when the cruise ends in seven days, you have no way to get home,” Patricia said. “It could be a system error. Or whoever purchased the package intended to add the return flight later.” “Who purchased it?” I asked, though I already knew. Patricia reviewed the details. “It was purchased by Michael Sullivan with a credit card in his name. Is he your relative?” “He’s my son,” I said, sadness and anger twisting together. “Oh,” Patricia said kindly, “then surely he’ll take care of buying your return ticket. But I recommend you contact him soon—flights from Miami to Chicago fill up quickly, especially this time of year.” Carl stepped in. “Would it be possible for Mr. Sullivan to buy his return ticket right now to be sure he has a seat?” “Of course,” Patricia said, typing for several minutes. “I have availability on a flight leaving Saturday at 3:00 p.m., the day the cruise ends. The cost would be $750.” “I’ll take it,” I said immediately, pulling out my card. As Patricia processed the purchase, Carl leaned close. “Our first real piece of proof. Michael deliberately didn’t buy your return. That shows intent.” When we left the office, we walked the deck to talk privately. The day was beautiful—bright sun, gentle breeze—but I couldn’t enjoy a second of it. “Carl,” I said, hands tight at my sides, “every piece of proof hurts. It’s like discovering over and over my own son wants me dead.” “I know,” he said, “but every piece also protects you. Now you have your return—and we’ve documented that Michael never intended you to come back.” That’s when my phone buzzed: a text from Michael.
