Critical reception
The Monthly Film Bulletin wrote: "The acting in this film is good; Robert Newton as the signalman depicts all the temptations to which the flesh is heir; his moveable face shows the continual struggle between his conscience and his love for his daughter. Here is a weak man who is stupid as well as cunning. Margaret Barton as the daughter is exactly what an overworked child would be. Simone Simon as the "mermaid" is a clever actress, clever in more senses than one, and unpleasant. To people who know the "Newhaven-Dieppe" channel crossing there is a certain thrill in the Southern Railway scenes, the arrival of the ship, the cranes, the signal-box, the trains are all there beautifully and technically perfect. And the background music is good and descriptive."[6]
In British Sound Films: The Studio Years 1928–1959David Quinlan rated the film as "average", writing: "Leisurely but gripping drama with rather unpleasant characters."[7]
