It was always a relief on the ward when midnight came, bringing the late-night caretakers in their faded scrubs and sensible shoes, carrying their little trays of sweet oblivion from bed to bed and room to room. They passed among the patients like the Sandman himself, leaving even the most devoted screamers sleeping peacefully. The silence wouldn’t last, but oh, it was sweet for a little while. The more damaged patients—the ones who’d been waiting years for sanity to make a house call, the ones who’d outlasted dozens of caretakers and might well outlast a dozen more—had had plenty of time to develop a tolerance for even the most potent sedatives. The worst could take doses that would knock an elephant out and be right back to screaming down the walls an hour later.
