[These notes were made in 1982:]. An adaptation of the two Mudd episodes of the series, plus about the same again in an original Mudd story. I always found these particular episodes particularly light stuff, and J.A. Lawrence (who, I feel, is really carrying out a literary bequest - she's James Blish's widow -rather than being a hard-core Trekkie) has kept the tone even and amusing and insubstantial. The last half deals with time-travel, which I find rather a disturbing subject, but it neatly ignores the philosophical issues.
