Stoker became interested in the theatre while a student through his friend Dr. Maunsell. While working for the Irish Civil Service, he became the theatre critic for the Dublin Evening Mail, which was co-owned by Sheridan Le Fanu, an author of Gothic tales. Theatre critics were held in low esteem at the time, but Stoker attracted notice by the quality of his reviews. In December 1876, he gave a favourable review of Henry Irving's Hamlet at the Theatre Royal in Dublin. Irving invited Stoker for dinner at the Shelbourne Hotel where he was staying, and they became friends. Stoker also wrote stories, and "Crystal Cup" was published by the London Society in 1872, followed by "The Chain of Destiny" in four parts in The Shamrock. In 1876, while a civil servant in Dublin, Stoker wrote the non-fiction book The Duties of Clerks of Petty Sessions in Ireland (published 1879), which remained a standard work. Furthermore, he possessed an interest in art and was a founder of the Dublin Sketching Club in 1879.
