Undercurrents — Frances Fyfield

For twenty years, Henry Evans has been haunted by a blurred but shining memory of his lost love, Francesca Chisholm. Now this shy American has come looking for her, in her hometown on the English coast. What he discovers is not what he expects.

Francesca is in prison for murdering her five-year-old son.

The verdict was never in doubt. Francesca confessed, admitted to pushing her own son off the pier, to drown in the dark undercurrents of the sea. Henry, though, can't believe it; it just doesn't tally with the woman he knew. And so he decides to stay to discover the truth.
