This is the story of one true love, that of Richard and Shivaun, honeymooning in America in a Honda Civic super-glued with chewy, fruity Skittles (a bowl of them is passed round in the fringe’s most blatant exercise in product placement), and its expiry in a new one.
Richard’s new partner “lives with” his old one, and he with hers: “You’ve been so kind being him for me that I’ll be her for you.” This interesting, poignant development is rather tacked on at the end, but the journey is pleasant enough, and Marsh is clearly a new name to watch.
