Dancing in the Dark — Stuart M. Kaminsky

In this installment of a 1940s Hollywood detective series, Fred Astaire hires Toby Peters to help him get rid of an incredibly untalented dance student, whose tutelage he has been forced to undertake by her threatening mafioso boyfriend. Luna has demanded dance lessons from Hollywood’s finest hoofer, and whatever Luna wants, Luna gets. Toby may not be a dancer, but he has no choice but to stay nimble and keep his feet moving.
