Sinister Street.

Sinister Street is a 1969 British television miniseries based on Compton Mackenzie's 1913-14 novel of the same name. Dramatised by Ray Lawler, the six-part serial stars Brett Usher, Gillian Hawser, Kate Lansbury, and Jo Kendall. Being the sole televised adaptation produced, all episodes were wiped and are believed to be lost. A psychological coming-of-age drama, two children, Michael Fane and his sister Stella, are born out of wedlock, something considered taboo at the time, but to rich parents.
