Again a practised period drama of innocence and intrigue, seasoned by elements of evil, this tells of apprentice doctor Humphrey Shadbolt's attempt to save Letty Rowan, seventeen, fragile and orphaned, who is destined for her aunt's coffee house which is devoted to less decorous forms of entertaining its clientele. On his visits to the coffee house, Humphrey is sure that Letty, while firm in her refusal to be rescued, does not appreciate the nature of the establishment. Earning extra money, by driving contraband goods by night, Humphrey is able to find a house for Letty, hopes to marry her. But in a raid by the excise men his partner is killed, Humphrey is wounded, and with Letty's suicide- a calf for Venus- he learns that it is his dead partner whom she had loved... Within its familiar frame of decorative drama, good deeds and evil doings, this provides entertainment-for rent and some sales.
