Our knowledge of the play The King In Yellow is largely restricted to its first act, and is not much. In The Repairer of Reputations it is said that the "banality and innocence of the first act" belies the awful effect of the rest. Thus any reconstruction of the play should have a first act that is not that strange, horrific or challenging, save, possibly, for its conclusion. In addition, there is a brief poem at the start of The Yellow Sign that could be part of the play, although it is unattributed, and an utterance of Hildred Castaigne that could conceivably be a quote from the play.
