At the medical center «Iliada» there was a rule: prescribe tests and procedures according to the information about patients’ account balances. Alla violated this requirement, and as soon as she reached for the «main thing of all,» her belongings were, within ten minutes, thrown into black bags and put outside the gate along with her. Alla never forgave Gattler, the owner of the center, for this cruelty. And her friends helped gather evidence of the acts being hidden in the back rooms of a prestigious center. The main hero of this operation was Buddy—the cat that was chipped: with the help of artificial intelligence, he managed to get into inaccessible places and obtain evidence recorded on the collar camera that had been installed for him. Everything turned out extremely complicated, and what Buddy uncovered stirred the imagination and perception. Read, dear readers!
