Murder, London Style; Dracula (Again); Aging Disease: TV

A murder mystery set in a tuxedoed 1930s enclave of London’s jazz-besotted aristocrats, the British miniseries “Dancing on the Edge” makes one thing emphatically clear: Chiwetel Ejiofor’s star-making performance in “12 Years a Slave” is no fluke.

While the series itself is hit and miss, the cast (and sumptuous period design) is first rate. “Dancing,” on Starz, features an ensemble that includes Matthew Goode, John Goodman and Jacqueline Bisset.
