But there was a simplicity of character and a fund of good sense in David which saved him from this latter fate, even though he quickly became the talk of the town, the man about whom the fashionable London world went mad. After acting with ever-increasing success in nineteen different parts, his London season came to an end for the time being, and in response to an urgent invitation he went over to Dublin, where the craze for him was so intense that, when a mild epidemic broke out, it was given the name of the Garrick fever. A second visit to that gay capital was even more successful, and Garrick finally returned to London with a clear £600 in his pocket. It was then that various difficulties beset him, chiefly owing to the bad management of the theatres and the endless quarrels between the principal actors of the day; but at last, thanks to the many friends who firmly believed in him, and whose faith he never disappointed, he was able to invest £8000 in Drury Lane Theatre, and to become its manager as well as its leading actor. His determination was to "get together the best company in England," and it is characteristic of him that he let no past jealousies or quarrels interfere with his selection. Even Macklin, who had violently attacked him with tongue and pen, was engaged, as well as his wife, and he skilfully smoothed down the sensitive feelings of the various ladies. He insisted on rehearsals, which hitherto had seldom been enforced, and he also insisted that players should learn their parts, a very necessary proviso. On the opening night he remembered the friend with whom he had entered London, when triumphs such as this had been undreamt of, and it was Dr. Johnson whom he commissioned to write the prologue, which he himself gave with splendid effect. Later on he loyally did his best to make a success of Johnson’s heavy and somewhat clumsy play "Irene," and thanks to his efforts and the money he freely spent on its staging, it ran for nine nights, so that the Doctor made the sum of £300. But with this the author was far from satisfied, and always declared that the actors had not done justice to their parts!
