Between the Lines

Graduation day. Amidst the generic well-wishes, you piece together four yearbook entries exchanged among a close-knit group of seniors. Someone is already dead, and a hit has just been ordered. What is the horrifying truth hidden between the lines? [Entry 1: Chloe's message in Arthur's yearbook] (Voted: Future Broadway Star) "I've decided to abandon New York and move to Paris! About our little secret... someone was snooping around. But don't worry, I handled it. As Nietzsche said: 'He who cannot obey himself will be commanded.' Have a great summer!" [Entry 2: Mark's message in Arthur's yearbook] (Voted: Most Quiet) "Just wanted to say you were right about me. Actually, I'm going to drop that bad habit. Considering my lack of self-control, I'm moving out of my bedroom. Kinda need to get away from the house next door anyway. Dude, I don't know if I should tell you this... It's whatever. Don't worry about it. I'm just waiting for the final grades! Take care!" [Entry 3: Jack's message in Arthur's yearbook] (Voted: Class Philosopher) "Congrats on getting into Yale. We're all going our separate ways now. There's a lot I want to say, but we'll have time. Please keep the past buried, and I wish you a bright future." [Entry 4: Arthur's message in Jack's yearbook] (Voted: Valedictorian) "Thanks for signing my yearbook, Jack! Congrats on getting into your dream school too. By the way, I heard Mark is moving. Probably because he knows Chloe is going to Paris. Honestly, I don't really like Mark. He has a really big mouth. Best of luck."
