Question: What American novelist published a genre work that mixed elements of science fiction and detective fiction,  Robert Creeley or Jonathan Lethem?

Essrog works, along with Tony, Danny and Gilbert, who call themselves the Minna Men, for Frank Minna—a small-time neighborhood owner of a "seedy and makeshift" detective agency—who is stabbed to death.
