The Shadows Over Sullivan

Dear Detectives,

Did you miss me? I certainly hope so because I have a brand-new mystery for you to crack. This one isn't just any case, it's one that's been buried in the shadows of Sullivan University, waiting for sharp minds like yours to uncover the truth.
While I'm off enjoying a well-deserved vacation, I need you to step in and do what you do best-solve the unsolvable. John and his friends are in deep, and they're counting on you to piece together the clues, follow the trail, and uncover what's really lurking beneath the surface. But be warned-this isn't a simple puzzle to solve. There are whispers in the dark, messages hidden in places no one has dared to look, and forces at play that don't want the truth to come to light.
Every case has its twists and turns, and this one is no exception. Pay attention to every detail, question every piece of evidence, and trust your instincts. Sullivan University has more secrets than anyone ever realized, and the deeper you dig, the more dangerous the game becomes.
Some mysteries refuse to stay buried, and some shadows stretch farther than you think. Are you ready to uncover what's been hidden for so long?
Stay sharp, detectives. John is counting on you. I'm counting on you.
