_Detective Story Magazine_ is a weekly publication. It is therefore a large market, and is constantly in need of short stories of 2,500 to 6,000 or 7,000 words, novelettes of 12,000 or 15,000, and novels of 25,000 words. Serials should run from 36,000 to 100,000 words in length, and break up approximately in about 12,000 word installments. It must not be deduced that only detective stories are needed for this publication. When one speaks of a detective story we think of a narrative which begins with the murder of somebody, the police being called in, and then the efforts of the police or the efforts of some wise investigator of crime to solve the mystery of who killed the deceased. Of course, this story with variations--if it is well done--is always acceptable. While we are dealing with it we might say that, in general, such stories are divided into two types, one in which the method is the predominating theme, and the other in which the motive is played up prominently. The first type of story suggests the puzzle. There is always a type of mind which revels in puzzles. A person mysteriously disappears from a room, and after wading through 60,000 or 70,000 words, mostly questions and answers, we learn that the method of removing the body was through, we will say, the fireplace, which was on hinges. Of course, this is the easiest type of detective story to write, and, as is quite obvious, it is written backwards. We mean by that, an author first evolves an ingenious method of killing some one, or of removing some one, and then builds about this a story, leaving the disclosure of the method of killing or removal to the end of the story. We think a far better way to do this story, and a way that interests more people, is to have the motive the predominating feature. The method by which, we will say, a young woman disappears, either through her own efforts or through the efforts of others, is interesting enough in its way, but that which interests the public generally, and her friends in particular, is not how she disappeared, so much as why she disappeared.
