The Squeaker (German: Der Zinker) is a 1963 West German-French crime film directed by Alfred Vohrer and starring Heinz Drache.

[1] It was part of a very successful series of German films based on the writings of Edgar Wallace and adapted from the 1927 novel of the same name.

The trail leads to the strange Mr. Sutton, owner of a zoological store that also carries predators and poisonous snakes.

During his investigation, Elford meets Mrs. Mulford, an older lady who tries to help ex-convicts, and Beryl, her niece, who writes crime stories and works as a court reporter.

To make Sutton confess, he is tricked by Mrs. Mulford in cooperation with the police into drinking what he believes to be poisoned tea.

In 1961, an initial treatment had been written by Egon Eis who had earlier also worked on the script for the 1931 film made in Germany.
