Although this story is full of suspense and plot twists, unfortunately there does not appear to have been any follow-up reports relating how Ladislaus de Doory dealt with his numerous difficulties.

By  United  Press.
    New York, March 8.--"Baron" Ladislau de Doory is in some litigation. During the past 24 hours application has been made for the annulment of his marriage today to Kathereen Dassori, aged 16. The girl's parents have threatened to have him arrested for desertion; the federal authorities have begun an investigation of his $1,000,000 United States Telephone Herald and Margaret Cline, an artist's model has announced she is about to sue the "nobleman" for breach of promise.
    The last seen of the "baron" by his young bride was when he packed up 112 pairs of trousers and left their Brooklyn flat. Mrs. De Doory says she has tired of being a "baroness."
