The Door Between is a mystery novel, published in 1937, and set primarily in New York City.
This is a very old, vintage book in good condition. The dust jacket is missing. There is an address written on the front and back cover pages, and a tear in the back cover page. The binding is coming loose at the title page, and the pages are darkened with age (see photos). However, the binding is intact overall, all pages are present, and there are no other marks, creases or tears throughout the book.
