Jerome sat down to write Three Men in a Boat as soon as the couple returned from their honeymoon. In the novel, his wife was replaced by his longtime friends George Wingrave (George) and Carl Hentschel (Harris). This allowed him to create comic (and non-sentimental) situations which were nonetheless intertwined with the history of the Thames region. The book, published in 1889, became an instant success and is still in print. Its popularity was such that the number of registered Thames boats went up fifty percent in the year following its publication, and it contributed significantly to the Thames becoming a tourist attraction. In its first twenty years alone, the book sold over a million copies worldwide. It has been adapted to films, TV and radio shows, stage plays, and a musical. Its writing style influenced many humorists and satirists in England and elsewhere.
With the financial security that the sales of the book provided, Jerome was able to dedicate all of his time to writing. He wrote a number of plays, essays, and novels, but was never able to recapture the success of Three Men in a Boat. In 1892, he was chosen by Robert Barr to edit The Idler (over Rudyard Kipling). The magazine was an illustrated satirical monthly catering to gentlemen (who, following the theme of the publication, appreciated idleness). In 1893, he founded To-Day, but had to withdraw from both publications because of financial difficulties and a libel suit.
In 1898, a short stay in Germany inspired Three Men on the Bummel, the sequel to Three Men in a Boat, reintroducing the same characters in the setting of a foreign bicycle tour. The book was nonetheless unable to capture the life-force and historic roots of its predecessor, and it enjoyed only a mild success. In 1902, he published the novel Paul Kelver, which is widely regarded as autobiographical. His 1908 play The Passing of the Third Floor Back introduced a more sombre and religious Jerome. The main character was played by one of the leading actors of the time, Johnston Forbes-Robertson, and the play was a tremendous commercial success. It was twice made into film, in 1918 and in 1935. However, the play was condemned by critics – Max Beerbohm described it as "vilely stupid" and as written by a "tenth-rate writer".[4]
