The Trial is a novel written by Franz Kafka from 1914 to 1915 and published in 1925. One of his best-known works, it tells the story of a man arrested and prosecuted by a remote, inaccessible authority, with the nature of his crime revealed to neither him nor the reader. Heavily influenced by Dostoevsky's Crime and Punishment and The Brothers Karamazov, Kafka even went so far as to call Dostoevsky a blood relative. Like Kafka's other novels, The Trial was never completed, although it does include a chapter which brings the story to an end.

The Metamorphosis (or The Transformation) is short story, sometimes regarded as a novella, by Franz Kafka, first published in 1915. It has been cited as one of the seminal works of fiction of the 20th century and is studied in colleges and universities across the Western world. The story begins with a traveling salesman, Gregor Samsa, waking to find himself transformed (metamorphosed) into a large, monstrous insect-like creature. The cause of Gregor's transformation is never revealed, and Kafka himself never gave an explanation. The rest of Kafka's novella deals with Gregor's attempts to adjust to his new condition as he deals with being burdensome to his parents and sister, who are repulsed by the horrible, verminous creature Gregor has become.
