When Suzanne Grandais spots husband Leonce Perret kissing another woman, she writes him a note that this is the last straw and leaves.
I hadn't realized that Perret, whom I know as a director of short subjects and longer movies with a tendency to hold his shots too long for my taste; his most famous movie is probably MADAME SAINT GENET, with Gloria Swanson. However, it turns out that he appeared in more than a hundred short subjects through 1916, often starrring as 'Leonce'.
It's a classically formed comedy, more about a situation that turns out well than anything that struck me as funny. However, given that who the woman Leonce as kissing is never revealed, it's possible that the film is missing at least a couple of titles.
