It opened in the West End of London at the Fortune Theatre on 19 April 1927 and ran until 2 June 1928.
[1] The exacting and difficult Maria Wislack is a widow who decides to take Richard away to her Scottish island for a month's trial "on approval" to see if they are compatible for possible marriage.
While there they meet Helen, who is in love with the Duke, and circumstances make all four of them stay on the island for the month.
Because of the bad behaviour of Maria and the Duke, Helen and Richard decide not to marry either of them and they leave them stranded on the island.
The Duke and Maria pretend to be romantically involved to make the other two jealous, but end up marrying each other instead.
