Basically, I have a scene in my head where Heridon's family goes on a summer cruise ship (their family friend just invited them to come tag along on their vacation) This ship is on a cruise line straight to Mexico. Heridon just wants to stay onboard, and he meets a college student named Lucy. They don't fall in love (he already has a love interest), but they become friends as they share common interests in anime, videogames, movies, as well as world history. On the way back, something happens and the ship is sinking. What it is, I have no idea yet, but the ship lists to to port, disabling all the lifeboats there. As the crew radios for help and tries to keep the passengers calm, Lucy begins to think how poetic all this is that the two of them are on a sinking ship like in the movie Titanic, and Heridon just loses it. He begins yelling about how there is nothing poetic about a tragedy, that it is disgusting and disrespects the dead. Oh, and they have to stop the bad guy. Why does the ship have to sink? To add to the drama and urgency. They have to stop the culprit from escaping justice, as well as escape the ship themselves. Let's assume they're near the Carribean Islands and are nowhere near the Gulf of Mexico just yet. My questions: #1- As this is a mystery, would it be a tad cliche to have Heridon solve a mystery onboard the ship? It may not be outright murder, could just be simple theft, but still...I suspect this is something Agatha Christe would've done... #2- While Heridon and Lucy do not fall in love, and they just help each other solve the mystery, would the fact that they're on a sinking ship at all scream Titanic? Even if the pair got off fine and the coast guard/navy/whatever managed to get to the scene in time? #3- I have absolutely no knowledge in marine vessels. What would cause a cruise ship to start listing/sinking? Would coastguards/navy be able to tow the ship back to port? If the ship's sinking like that, would they still be able to get people into lifeboats on the opposite side of the ship or no? Would there really be a sense of urgency, since most everyone would likely survive a sinking cruise ship in this day and age? Thoughts?
