Back in the Big City

Fuming and quite shaken after intercepting an elaborate scam to steal my mother's bank card this morning.  Thank God I was here to answer a call from a well spoken woman claiming to be from Nat West telling me that, as had already been discussed with my mother, a courier would be delivering her new card and picking up the deactivated one.  Minutes later the 'courier' came to the door with a dodgy looking card embossed with my mother's name name (minus one initial) wrapped in a blank piece of paper.  He left empty handed.  I only wish I had had the foresight and courage to snap a quick photo of him.   What kind of evil people prey on the elderly?
