39 Hilldrop Crescent. It sounds like a pleasant English address, maybe a small cottage off a cobblestone street, with flowers in the windowboxes.

On March 3, 1943, tragedy struck in London, at the Bethnal Green Tube station. People on their way down to the station to seek shelter from a air raid were caught in a crush when one person fell.

But the ghosts of this tragedy do their own remembering late at night, when the trains fall silent. Join me for a walk around this touching monument.
