A writing workshop taught by Judson Merrill, one of Guild Hall’s five artists-in-residence, will take place on four consecutive Thursdays starting April 5 from 6 to 8 p.m. Titled “Writing Workshop Real Fiction: Writers, Readers, and the Battle Over Truth,” it will examine the ways fiction uses and abuses ideas of truth and authorship, experiment with those techniques, and discuss the creative and social benefits as well as the pitfalls.
