"Dark Legacy" proves a mere trifle as the first season winning streak dies down, dual roles for Harry Townes ("The Cheaters") yet neither truly effective in an occult story that drags its feet to an underwhelming climax, the last of three series appearances from Alan Napier ("The Purple Room"), here reteamed with Doris Lloyd from "Hay-Fork and Bill-Hook." Dying sorcerer Radan Asparos wills his most prized possession to his nephew Mario, at this time a struggling stage magician wed to assistant Monika (Ilka Windish), a book of spells that summon the demon Astaroth in exchange for a life. Cousins Doris Lloyd and Richard Hale ("The Incredible Doktor Markesan") and butler Milton Parsons all vanish from the scene with attorney Napier once the estate is dealt with, leaving Mario to go through his inheritance page by page with fellow magician Toby Wolfe (Henry Silva), to the chagrin of a hysterical Monika. Required to come up with something fresh to maintain his position for nightclub owner Vince Fennaday (Ned Glass), Mario chooses to call forth the forces of darkness while alone in his study, claiming the life of Monika's dog Peter to which he lies and states that the mutt ran away. His new tricks are masterful yet truly frightening, and his arrogance in proving his newfound abilities to the disbelieving Wolfe lead to self destruction. The old age makeup for Radan evokes only chuckles, while Townes' over the top rantings show director John Brahm struggling to reign in a believable performance, but the next two episodes would be so good that this minor footnote would be easily forgotten.
