Peeper is a 1975 American mystery comedy film directed by Peter Hyams and starring Michael Caine as Leslie C. Tucker, a bungling private investigator.

[5] A send-up of 1940s films noirs, Peeper was a box-office failure that jeopardized Hyams's career and almost prevented him from obtaining funding to produce Capricorn One.

Tucker's search leads him to two sisters, daughters of a rich Beverly Hills widow.

Ultimately everyone ends up on a cruise ship headed to South America and the various mysteries are resolved.

[6] The producers had worked with Peter Hyams on Busting and hired him to rewrite W.D.
