Bulldog Drummond Escapes

This is one of 8 Bulldog Drummond adventures produced by Paramount in the late 1930s, and sold to Congress Films (II) in mid-1954 for re-release; Congress redesigned the opening and closing credits, in order to eliminate all evidence of Paramount's ownership, going so far as to even alter the copyright claimant statements on the title cards; Congress, in turn, sold the films to Governor Films for television syndication. Along the way, Paramount, having disowned the films, never bothered to renew the copyrights, and they fell into public domain, with the result that inferior VHS and DVD copies have been in distribution for many years, from a variety of sub-distributors who specialize in public domain material.

Near the beginning, Drummond sees a dead body in the moor and sees it sink. At the end, Drummond leaves without telling about the corpse or tell anyone where the body is located. (But Col. Nielson does mention the "murdered chauffeur" well before the end.)
