What was Isak Dinesen's first book?

Isak Denison is the pen name used by Karen Blixen, a Danish author. Her first book, which was finished in 1933, was Seven Gothic Tales. She had difficulty finding a publisher, but in 1934, it was finally published in the United States. Once it was chosen as a selection for Book-of-the-Month Club, the book started selling well and was widely known in the United States. After publication in the United Kingdom, Blixen worked on a Danish version, since she couldn’t find a translator that she was happy with. Danish critics were annoyed that she first published the book in another country, and her subsequent books were either published in Danish first, or they were published in Danish and English at the same time.

Isak Dinesen's first book was called Seven Gothic Tales. She wrote it in 1933, and she initially had trouble finding a publisher because the stories were considered too odd. However, it was published in New York in 1934, where it had high sales due to becoming a Book of the Month Club selection.
Isak Dinesen's real name was Karen Blixen. Although she was Danish, she wrote the book in English, believing this would give her a wider audience and earn her more money.
The seven stories in Seven Gothic Tales show the influence of nineteenth-century writers of mysterious, uncanny tales, such as Edgar Allen Poe and E. T. A. Hoffman. The stories featured ghosts and what was deemed a peculiar eroticism.
Dinesen is much more famous for her second novel, Out of Africa.
