The novel The Promise (Requiem for the Fifties) / Slib (rekviem na padesátá léta) is an intentional allusion to Friedrich Dürrenmatt’s novella The Pledge: Requiem for the Detective Novel) / Slib (rekviem na kriminální román), and at the same time it is about a promise unfulfilled. The novel is set in the author´s fateful town of Brno, mainly in the middle years of the twentieth century. The threads of the diversifying plot are pulled along by alternating narrators who weave together a story rooted in the times of emerging totalitarianism, with its omnipresent informers. The architect Kamil Modráček is subjected to a terrible test – he confronts the death of his sister as a consequence of a police interrogation. The story then changes into an absurd-symbolic scene on revenge, the results of which assume massively questionable outlines.
