In the one-and-onlyOne Step Beyond episode to feature a "monster" (albeit very briefly, and with a documented real-life incident backing up the decision), the Parish family goes to great lengths to hide the fact that their son is apparently a half-human, half-fish mutant. Out of love for her unfortunate son, Margaret Parish (Augusta Dabney) turns to an unorthodox doctor-hypnotist named Edward Brown (David Lewis). Believe it or not, this is a "Christmas Show", replete with a near-miraculous finale.
