  In addition to being a widely recognised novelist, Milan Kundera has also
authored three pieces for theatre: The Owners of the Keys (Majitel\'e
kl\'i\v{c}\r{u}, 1961), The Blunder (Pt\'akovina, 1967), and Jacques and his
Master (Jakub a jeho p\'an, 1971). In recent years, however, the hypothesis has
been raised that Kundera is the true author of a fourth play: Juro
J\'ano\v{s}\'ik, first performed in a 1974 production under the name of Karel
Steigerwald, who was Kundera's student at the time. In this study, we make use
of supervised machine learning to settle the question of authorship attribution
in the case of Juro J\'ano\v{s}\'ik, with results strongly supporting the
hypothesis of Kundera's authorship.
