Note on the circumstances of production:
'Last year the drama board of the Lyceum Club in London sent a request to the Melbourne Lyceum Club for plays written by members for production at the Lyceum Club. Miss Handley's was one of the plays sent.' ('Australian Play', Argus, 21 May 1931, p.3).
A Clue There Was:
Some Australian newspapers note that A Clue There Was was produced in London as an opening to A.A. Milne's Belinda, where British newspapers (and associated sources) record that play as Mr and Mrs Er-Smith. Conversely, no play by the title Mr and Mrs Er-Smith was produced in Australia. It is possible that these two works are the same drama with different titles, but more information is needed before this can be confirmed.
