Differential of a Dying Mind
case one:
The rain hammered against the windows of Princeton-Plainsboro Teaching Hospital hard enough to make the fluorescent lights seem colder. The emergency department buzzed with the usual chaos—stretchers squeaking across linoleum, nurses calling out vitals, a child crying somewhere down the hall.
And through all of it, Dr. Gregory House moved like he owned the building.
Limp.
Cane.
Sneer.
His faded Rolling Stones t-shirt was hidden under a wrinkled blazer that looked like it had lost a fight with a laundry basket. A bottle of Vicodin rattled softly in his pocket as he pushed past a nervous intern.
“Congratulations,” House muttered without looking at him. “You’ve mastered the ancient medical art of standing in the way.”
The intern stumbled aside.
House popped a pill dry and entered the diagnostics conference room where his team was already waiting.
Dr. Eric Foreman sat at the table, arms crossed, expression unreadable. Dr. Allison Cameron flipped through a patient chart with growing concern. Dr. Robert Chase leaned back in his chair, balancing a coffee cup on his knee.
On the whiteboard was one sentence:
31-year-old female — seizures, hallucinations, respiratory collapse.
House tossed his cane onto the table with a loud crack.
“Alright,” he drawled. “Who’s dying and why are they boring?”
Cameron frowned. “Female patient, Melissa Grant. Admitted thirty minutes ago after collapsing during a corporate presentation. She had tonic-clonic seizures in the ambulance and—”
“Corporate presentation?” House interrupted. “So death was preferable.”
Chase smirked into his coffee.
Cameron ignored him. “MRI is clean. No history of epilepsy, drug use, or psychiatric illness.”
Foreman slid another file across the table. “Blood oxygen dropped suddenly in the ER. They had to intubate.”
House glanced at the chart for all of two seconds before tossing it aside.
“Okay, she’s poisoned.”
Foreman blinked. “That’s your theory based on what?”
“She works in finance.” He stated.
“That’s not evidence.” DR. Eric foreman corrected.
“It’s motive.” House implied.
The door burst open.
Lisa Cuddy strode in carrying a tablet and the kind of patience that had already been exhausted before breakfast. Her heels clicked sharply against the tile.
“Please tell me you’ve actually started working.” She said exhaustively.
House leaned back in his chair. “We’re brainstorming. Chase thinks she’s hot. Cameron thinks she’s tragic. Foreman thinks I’m wrong. It’s a beautiful democracy.”
Cuddy crossed her arms. “Clinic duty.” She demanded.
“No.” House countered smugly
“You skipped three shifts.” Cuddy rolled her eyes fatigued.
“I was busy.” House combated
“You were playing guitar in your office.” Cuddy said exasperated.
House pointed his cane at her. “Therapeutic guitar.”
“For you.” Cuddy smirked.
“For humanity.” House defended.
Cuddy stepped closer, lowering her voice. “House, a patient nearly died waiting for you because you ignored your pager.”
House’s expression flickered for just a second—not guilt exactly, but awareness. Then the mask snapped back into place.
“And yet now she has the best doctor in the hospital. You’re welcome.” He said with a shit eating grin on his face.
Foreman exhaled quietly. Chase stared at the table to avoid smiling.
Cuddy looked like she wanted to strangle him with his own cane.
“You have two hours before clinic duty,” she said tightly. “And if I find out you’re running unauthorised tests again—”
“You’ll glare at me with those giant disappointed eyes?” he defied.
“House.” She replied clearly annoyed.
He grinned.
She turned sharply and walked out.
The room stayed silent for a beat after the door slammed.
Then House looked back at the board.
“Hallucinations, seizures, respiratory failure…” He tapped the cane rhythmically against the floor. “Something’s missing.”
Cameron tilted her head. “What?”
House’s eyes narrowed—the shift his team recognised instantly. The moment the puzzle stopped being abstract and became personal.
“The presentation.” He said outwardly thinking.
Foreman frowned. “What about it?”
“She collapsed during the presentation, not before, not after.” House stood suddenly despite the pain shooting through his leg. It showed for half a second in the tightening of his jaw.
“Which means,” he continued, “either somebody in that room poisoned her…”
He grabbed his cane and limped toward the door.
“…or the room poisoned everybody.”
Chase stood. “Where are you going?”
House smirked without turning around.
“To break several laws before lunch.”
He threw out into the most shit eating grin over his shoulder as he walked out the door.
