And here is the deepest cut: the lock is for your own protection. That's what the automated voice says, after the jazz. "We've locked your card to keep your money safe." As if the thief is you. As if your own wallet has been turned into a snitch. The bank has become a parent who reads your texts "for your safety." The lock is a leash disguised as a shield.

And now you are locked out of your own life.

You pocket the card. It feels heavier now. Not because of the plastic. Because of the key. And because you know—you know—that somewhere, in the silent arithmetic of the bank's servers, Kevin is already watching your next move.

Three words on a cracked iPhone screen, glowing in the grey London drizzle. NatWest card locked. Not "temporarily unavailable." Not "suspicious activity detected." Just locked. A small, final thud of a digital bolt sliding shut.

You sit on a wet bench near the station. The rain has that vertical, exhausted quality of late autumn. You try to remember a time before the card. Before PINs and contactless limits and two-factor authentication. When money was a folded note in a coat pocket, warm from your thigh. When a "lock" meant a brass thing with a key, and you knew exactly who had the other one. Now the key is held by a machine that has never been cold, never been hungry, never stood in a queue with a rapidly melting ice cream and felt the slow creep of shame.

Eventually, after 22 minutes, a voice. You recite your mother's maiden name, the last four digits of a card you can't use, the postcode of a house you left ten years ago. The voice says, "I've unlocked it for you. You should be able to use it in the next ten minutes."

The app says: "Call us." The hold music is a smooth jazz approximation of mercy. You wait. Twelve minutes. Eighteen. Your phone battery dips below 20%. You imagine the call centre in a fluorescent-lit office in Glasgow or Mumbai, where a human being named Priya or Dave is typing your fate into a system that doesn't blink. "I just need you to verify three recent transactions." But the transactions are yours. Of course they are yours. Who else would buy anti-dandruff shampoo and a packet of digestives at 9:47 PM?
