Many of Merrick's works are about the stage which were influenced by his two years of work there as an actor and actor-manager. For example J. M. Barrie said, "The stage figures so prominently in the novels of Leonard Merrick that most of his readers have imagined that he must have had lengthy experience in the profession. Such is not the case, Hayden Church writes in a letter to the American press. He was an actor for only two years. He was born stage-struck, and, at the age of 20, got the famous Augustus Harris to give him a chance in an English touring or "road" company. He was almost dismissed by the manager in charge, but another member of the company put in a good word for the youth. This was none other than Arthur Collins, now manager of the Drury Lane theatre in London." (see Barrie, J. M. (August 1918). "Booming Leonard Merrick Into Literary Immortality". Current Opinion. 65 (2): 115-116.).
