The Wrestler’s Cruel Study
By Stephen Dobyns. Poet and noir mystery novelist Dobyns branches out into philosophical farce in this ensemble-cast comedy set in early 1990s New York City, where wrestling matches re-enact early Christian disputes about the nature of evil, and anyone's life might unwittingly mimic a Grimm's fairy tale. What holds this capacious story together is the idea that truth is only manifested through artifical personae and constructed narratives—what wrestlers call their Gimmicks—and if there is free will, it consists of noticing your Gimmick and maybe choosing a different one.
