Two princesses are on the lookout, with a heavy heart. The return of their younger brother does not bode well, because he has been ordered home by their grandmother, the old queen.

Is she going to take the little prince with her to her quarters, behind the enormous door? Will he disappear without a trace, like so many before him?

Perhaps there is nothing to fear. Perhaps the princesses are wrong. Perhaps they are two blind fish in a murky pond. They have never seen the queen, and never dared to look behind the great door, where they believe death reigns.

Maurice Maeterlinck, the only Belgian writer who ever received the Nobel Prize for Literature, wrote La Mort de Tintagiles (1894) as a short drama for the marionette theatre. The short story, that has all the qualities of a thriller, plays on the fear of the unknown and tells of the power of love, that conquers fear. Locked (Slot) is a location project in which lighting and sound conjure up an eerie castle, full of mystery.
