At 4:47 a.m., a steady, indifferent tone cuts through the eleventh-floor corridor of St. Alderic's Hospital. Nurse Iris Tanaka knows that sound. Every nurse on the night shift does , the single continuous note that means something inside a body has stopped agreeing with itself. She and orderly Pete Salazar sprint toward OR-3, but by morning the death is just one more line in a logbook no one reads too carefully. Then another patient flatlines. Then another. And another. As the bodies accumulate, Iris and Pete begin to see what the administration is desperate to hide: the deaths are not random, the monitors are lying, and the hospital's new consulting patient, Silas Crane, seems to know exactly why. The deeper they dig, the more the walls close in , Renata Doss buries questions in paperwork, a stranger named Rook watches from the parking garage, and a powerful senator arrives with an agenda that has nothing to do with saving lives. With the dead refusing to stay accounted for and the living running out of time, Iris must choose between her career, her conscience, and a truth that could bring the entire hospital down with it. In a place where every heartbeat is monitored, the most dangerous sound is silence.
