A faint hiss. A chemical heat rose from the sink, along with a sulfurous, greasy smell. Lena stepped back and closed the bathroom door to keep her cat away. The mixture bubbled and churned inside the pipes for about fifteen minutes, dissolving the organic gunk into a soapy, liquid mass.

After the bubbling stopped, she ran cold water for two full minutes. The water swirled—hesitated—then vanished with a final gulp . Clear. Fast. Clean.

Lena’s Sunday started with a quiet cup of coffee and the plan to make her famous slow-cooked lamb shanks. But the moment she ran the tap to rinse the chopping board, the water sat there. And sat. A greasy, foul-smelling pool that rose rather than drained.
