Embassy Theatre

The Embassy Theatre in Swiss Cottage, London, was opened as a repertory company in September 1928.

In December 1930 Black Coffee, the first stage play by Agatha Christie, premiered there. It was produced by André van Gyseghem, with Francis L. Sullivan as Poirot and also featuring Donald Wolfit.

Mary Broome, by Allan Monkhouse, was played there in December 1931. This was a sudden and (still) unexplained substitution for the play originally announced, namely Chimneys, by Agatha Christie.
