Agatha Christie: Murder in the Making: More Stories and Secrets From Her Notebooks by John Curran Page B

Gong’/‘Dead Man’s Mirror’.In Chimneys she makes even more drastic alterations to the solution of the original; the character unmasked as the villain at the end of the novel does not even appear in the stage adaptation.
    Some correspondence between Christie and Edmund Cork, her agent, in the summer of 1951 would seem to indicate that there were hopes of a revival, or to be strictly accurate, a debut of the play, due to the topicality of ‘recent developments in the oil business’; this is a reference to one of the elements of the plot, the question of oil concessions. But further developments in connection with a staging of the play, if any, remain unknown and it is clear that until Calgary in 2003 the script remained an ‘unknown’ Christie. The remote possibility that the script preceded the novel, which might have explained the unlikely choice of title for adaptation, is refuted by the reference in the opening pages of notes by the use of the phrase ‘Incidents likely to retain’.
    There are amendments to the original novel in view of the fact that the entire play is set in Chimneys. As the play opens a weekend house party, arranged in order to conceal a more important international meeting, is about to begin, and by the opening of Act I, Scene ii the murder has been committed. And, in a major change from the novel, Anthony Cade and Virginia Revel are the ones to find the body, although they say nothing and allow the discovery to be made the following morning. In a scene very reminiscent of a similar one in Spider’s Web , Cade and Virginia examine the dead body and find the gun with Virginia’s name; in view of the danger in which this would place her, they agree to remain quiet about their discovery. In effect, Act II opens at Chapter 10 of the book and from there on both follow much the same plan.
    A major divergence is the omission of the scenes involving the discovery and disposal, by Cade, of the blackmailer’s body. In fact, the entire blackmail scenario is substantially different. But whether written or staged, it is an unconvincing red herring and it could have been omitted entirely from the script without any loss. Other changes incorporated into the stage version include the fact that Virginia has no previous connection with Herzoslovakia, an aspect of the book that signally fails to convince. The secret passage from Chimneys to Wyvern Abbey is not mentioned, the character Hiram Fish has been dropped and the hiding place of the jewels is different from, and not as well clued as, that in the novel.

    The Cast of Characters and Scenes of the Play from a 1928 script of Chimneys .
    The notes for Chimneys are all contained in Notebook 67. It is a tiny, pocket-diary sized notebook and the handwriting is correspondingly small and frequently illegible. In addition to the very rough notes for some of The Thirteen Problems the Notebook contains sketches of some Mr Quin short stories, as well as notes for a dramatisation of the Quin story ‘The Dead Harlequin’. Overall, the notes for Chimneys do not differ greatly from the final version of the play, but substantial changes have been made from the original novel.

    The entire action of the play moves between the Library and the Council Chamber of Chimneys. The opening scene, which does not have an exact equivalent in the novel, introduces us to Lord Caterham, Bundle and George Lomax, the immensely discreet civil servant, arranging a top-level meeting
