Having quickly made his name and fortune, in 1776 Sheridan bought David Garrick's share in the Drury Lane patent, and in 1778 the remaining share; his later plays were all produced there. In 1778 Sheridan wrote "The Camp", which commented on the ongoing threat of a French invasion of Britain. The same year Sheridan's brother-in-law Thomas Linley, a young composer who worked with him at Drury Lane Theatre, died in a boating accident. Sheridan had a rivalry with his fellow playwright Richard Cumberland and included a parody of Cumberland in his play "The Critic". On 24 February 1809 (despite the much vaunted fire safety precautions of 1794) the theatre burned down. On being encountered drinking a glass of wine in the street while watching the fire, Sheridan was famously reported to have said, 'A man may surely be allowed to take a glass of wine by his own fireside.' Sheridan was the manager of the theatre for many years, and later became sole owner with no managerial role.
