(U.S.title: The Public Eye) is a 1972 British comedy-drama film directed by Carol Reed and starring Mia Farrow, Topol and Michael Jayston.

[1] Adapted by Peter Shaffer from his 1962 play The Public Eye, the picture marks Carol Reed's last completed film.

Set in London, it is the story of Charles, a successful but rather stuffy businessman, who meets and marries Belinda, a free-spirited American woman.

However rather than abandoning the case, the detective begins an elaborate game of cat and mouse with the complicity of the wife.

The detective finally informs Charles that his wife never had an affair, and merely goes on solitary exploratory walks around the city.
