A mysterious man arrives in London and, in a freak accident, gets electrocuted on an underground train and loses his memory. A young lady called Sally Nightingale feels responsible, and brings him home to her mother. But in a strange twist of fate it transpires that her mother is the man's ex wife, whom he left twenty years earlier in unhappy circumstances. The old attraction is there, but what will happen if and when his memory returns? A highly melodramatic plot, but with a deft comic touch, a host of vibrant characters, and a large dash of romance...

Sidney Clopton Lanier was an American musician, poet and author. He served in the Confederate army, worked on a blockade running ship for which he was imprisoned (resulting in his catching tuberculosis), taught, worked at a hotel where he gave musical performances, was a church organist, and worked as a lawyer. As a poet he used dialects. He became a flautist and sold poems to publications. He eventually became a university professor and is known for his adaptation of musical meter to poetry. Many schools, other structures and two lakes are named for him.
