In “London Embankment at Night,” light is beckoned from a phone booth by the nighttime secrets held in tree-shrouded shadows. The Embankment of London’s River Thames provides sightseeing delights of Westminster Abbey, Big Ben and St. Paul’s Cathedral. The river flows around the city, its Embankment dotted with lampposts and statues decorated with nautical designs. Its romantic wrought-iron benches are also a haven for lovers, along with its amorous evening shadows.
