Jeffares added that Boyle treated political trickery in a farcical way in The Eloquent Dempsey, which was produced in 1906, as was The Mineral Workers.
The latter got "good dramatic results from placing a returned Irish-American engineer full of modern ideas...up against the locals' resentment of change.
"[3] In 1907, at the time of the Playboy Riots, Boyle withdrew his plays from the Abbey, but was encouraged to return by W. B. Yeats and Lady Gregory.
[5] The catalogue of the National Library of Ireland shows that Boyle wrote a one-act comedy called Tongue-Tied, perhaps around 1920.
It also contains a letter from Boyle dated January 1921, in which he declined an invitation to lecture before the National Literary Society because of the state of his health.
