PROLOGUE
ISABELLA
Geneva, Switzerland
Six Weeks Ago
The moment I discover my mentor has weaponized my life's work and sold it to terrorists is unremarkable—just me, cold coffee, and his unlocked computer glowing with evidence that will get me killed.
Fluorescent lights hum overhead while I lean back in my chair, rubbing eyes that burn from staring at compound structures all day. Outside the facility's reinforced windows, Lake Geneva stretches dark and still under a moonless sky. Most of the building sleeps—just security making rounds and obsessive scientists like me who've forgotten what reasonable working hours look like.
My aerosolized delivery system finally stabilized days ago. Medical-grade precision, particle size optimized for deep lung penetration, dispersal radius controllable down to the meter. Designed to deliver life-saving treatments to quarantine zones, disaster sites, anywhere traditional methods fail.
At least, that's what I believed when I signed the contract.
My coffee's gone bitter in the mug beside my keyboard. The taste makes me grimace, but I drink it anyway while pulling up tomorrow's presentation files. The investors want proof of concept before releasing the next round of funding. Standard procedure—this dance is familiar.
Except my laptop's running slower than usual tonight.
Frowning, I check the system monitor. Processing power's being diverted. Background tasks running that shouldn't be. My pulse kicks up a notch as I trace the activity back to a networked connection I didn't authorize.
Someone's accessing the shared server. After hours. From Dr. Emil Rousseau's workstation.
Emil left only an hour ago. Mentioned something about his daughter's recital, kissed my cheek in that absent professorial way he has, reminded me not to work too late. He's been my mentor since Zurich, the one who recruited me to this project, who promised me we'd change emergency medicine forever.
His computer's still logged in across the lab.
Professional curiosity wars with the instinct that something's wrong. The same instinct that made me choose science over my family's shipping empire, that pushed me through every glass ceiling academia threw up, that refuses to accept things at face value.
Crossing the pristine white floor between our stations takes seconds that feel like minutes. Emil's workspace looks exactly as he left it: journals stacked precisely, coffee mug washed and drying on the small towel he keeps for that purpose, family photos arranged just so. Everything in its place.
Everything except his screen, still glowing with an active session.
My fingers hover over his keyboard. This violates every protocol we have. Privacy, professional boundaries, basic respect. But that background process is pulling data from ourshared research files. Large files. The kind that contain months of proprietary work.
The screen wakes at my touch.
Password-protected folders fill the display. Encryption I don't recognize. File names that mean nothing: Project_Cascade_Final, Delivery_Specs_Modified, Buyer_List_Confirmed.
Buyer list?
My breath stops. We don't have buyers. We have investors. Medical foundations. University partnerships. Government health organizations reviewing our work for potential emergency response applications.
Not buyers.
My hand moves before my brain catches up, clicking on the first file. Encrypted. Of course. But Emil's terrible with security protocols—brilliant with chemistry, catastrophically lazy with digital hygiene. His daughter's birthday unlocks nothing. Wedding anniversary, nothing. The facility code he uses for everything despite IT's constant warnings.
The file opens.
Technical specifications fill the screen. My specifications. My delivery system. But the application parameters have been modified.
My dispersal radius was five hundred meters, controlled and precise for medical deployment. This shows two thousand meters. My particle density was optimized for therapeutic absorption—point-three microns. This reads point-one-five microns. Weaponized aerosol density.
Chemical payload capacity makes my stomach lurch as the numbers scroll past. Where I designed slots for antibiotics, antivirals, emergency medications, someone's entered different designations.
VX-class compounds. Sarin derivatives. Biological agent designations I recognize from my coursework on defensive countermeasures. Chemical formulas that exist solely to kill efficiently and silently.
My elegant, precise, life-saving technology has been turned into a weapon of mass murder.
