"Wish You Were Here" is basically a solo Tara adventure like "All Done with Mirrors," right down to burdening her with an incompetent assistant for the unavailable Steed. Charles Merrydale (Liam Redmond, "Small Game for Big Hunters"), Tara's uncle, is among a select number of guests in an Elizabethan hotel who are held prisoner out in the open, with his business being taken over by Stephen Kendrick (Gary Watson, "Death on the Slipway," "Immortal Clay," "Lobster Quadrille"). Any attempts to check out meet with flat tires, staged 'accidents,' or simply lame excuses from the manager (Dudley Foster, "The Hour That Never Was" and "Something Nasty in the Nursery"). Tara's arrival meets with success once the experience of working alongside Steed is put to ingenious use. A marvelous Tony Williamson script, embellished by an excellent cast of familiar faces, including Robert Urquhart ("Castle De'ath"), Richard Caldicot ("A Funny Thing Happened on the Way to the Station"), Derek Newark ("Trojan Horse" and "From Venus with Love"), and David Garth ("The Big Thinker" and "How to Succeed....at Murder").
