It was a Saturday in February 2020 when the flood came. It had been a wet winter, so wet it seemed that before the month was out, the brown trout of the River Taff might be washed clean out into Cardiff Bay before the fishing season had even begun. But this is Wales. People are used to a spot of rain. No one realised how bad it would get.
For two days, it hammered on the windows of the houses at the top of the South Wales Valleys, where people tucked in their children before a sleepless night. It poured into the rivers at the bottom. By the time the rain departed again, many people would be standing in water up to their knees.
