Stanley Houghton’s bracingly unsentimental Hindle Wakes failed twice on Broadway, expiring after 30-odd performances in both 1912 and 1922. In a new century, the Mint Theater Company is demonstrating that this little-known play with its perplexing title is a compelling period piece. Directed by Gus Kaikkonen and performed with unrelenting gusto, Hindle Wakes is likely to prove more enduring this time around.
