In Elaan of Troyius he played Petri, the green-skinned ambassador of Troyius, charged with teaching civilised manners to Elaan, the Dohlman of Elas, before her arranged marriage to his ruler. Elaan stabs him for his trouble, and from his sickbed Petri refuses to have anything more to do with her, leaving the task to Kirk.
