Great episode, but radio dramas prominently featuring chattering, squealing rats always get at least one extra star from me (Three Skeleton Key being the classic of the form.)

Ralph Bell, as mentioned elsewhere, has one of the great voices, and plays a psychotically angry SOB to perfection here. There's unintentional comedy in the scenes where the love interests exchange vows of love and desire which are barely audible over the squeals of 150 rodents--couldn't they go somewhere a little more conducive to romance for the moment--but that just adds an extra layer of entertainment.

Again, great episode IMHO.
