Byleth, Il Demone dell’Incesto - 1972 - 5/10
AKA - Byleth, The Demon Of Incest

Dolores, the busy village prostitute, is savagely murdered after another sensual transaction.
Next comes, well, let’s not get premature with the slippery details.
Rather, focus on Barbara, returning from England and continental travels.
To the glistening delight of her brother, Duke Lionello.
The siblings display a very cozy relationship.
Unfortunately, Barbara returns with a new husband, and Lionello becomes curious.

Abundant, full figured nudity camouflage a thin, derivative whodunit.
Pace plods along, but the scenery is lush (including the nude sybarites).
Midway, the script offers a macabre suggestion, but it doesn’t really help.
