From creepy book to noirish film to a musical?

If you need to know how a story about an ex-convict murders his wife,  stalks two children who happen to have a whole lotta loot and pretends to be a minster can turn into a musical, we have an answer. Or rather, Lyric Stage does. Stephen Cole and Claibe Richardson have turned the Davis Grubb’s novel into just that. We’re curious how they will pull it off, because there’s  not a whole lotta happy going on in the story. And aren’t musicals all about the happy?
DEETS: Irving Arts Center’s Carpenter Hall, 3333 N. MacArthur Blvd. 2:30 p.m. $25–$50. LyricStage.org.
