Colman, George Arthur Griffenhoof (the younger) The Iron Chest (1796) This is an adaptation of William Godwin's novel, Caleb Williams . With music by Stephen Storace. When Colman published The Iron Chest , he attacked Kemble for sabotaging the play but, as it turns out, he was genuinely ill and the audience excused him as did reviewers who were critical of the play itself. For an account of this, see also The Oracle (14 March 1796); The Star (14 March 1796); and The Morning Herald (21 March 1796). On 13 March 1796 Godwin records having tea at Kemble's with Twiss and discussing 'theatrical illusion'.
