Leah Kleschna
Leah Kleschna is a drama in five acts by C.M.S. McLellan produced for the first time on Broadway by Minnie Maddern Fiske, Harrison Grey Fiske and the Manhattan Company with set design provided by Frank E. Gates and E. A. Morange. The play opened under the direction of Mr. Fiske at the Manhattan Theatre on December 12, 1904, and had an original run of 131 performances. Leah Kleschna returned to Broadway at the same venue in September 1905 for an additional 24 performances and in 1924 for a short run at the Lyric Theatre with Helen Gahagan as Leah. Leah Kleschna opened  to positive reviews in London on May 2, 1905, at the New Theatre with Lena Ashwell in the title role. The production by  Charles Frohman's company resulted in the threat of legal action by Mrs. Fiske who claimed she had purchased the English rights to the play. On December 10, 1913, the silent film Leah Kleschna premiered with Carlotta Nillson playing Leah, House Peters as Sylvaine and Hale Clarendon as Kleschna. The picture was directed by J. Searle Dawley and produced by the Famous Players Film Company. A year or so later Nillson played Leah once again in a Daniel Frohman road production of the play. Synopsis

Leah Kleschna is the daughter of a manipulative master jewel thief  who has raised her to follow in his footsteps. When Leah is confronted by Paul Sylvaine, the owner of the house her father had sent her to rob, she is persuaded to contemplate her life as a thief. Eventually Leah returns the jewels she stole, abandons her father and leaves Paris to work on the country farm she was raised on. The story comes to a happy conclusion when a few years later Sylvaine reunites with Leah and a romance ensues. Reception
The New York Times, December 13, 1904, wrote:
"Evidence of a popular success were not wanting at the Manhattan Theatre last evening when for the first time was seen a new play by C. M. S. McLellan, hitherto known to New York playgoers as "Hugh Morton," author of several comic opera books, among which the most notable perhaps was that of The Belle of New York which endured a large measure of success, both here and in London. On this occasion Mr. McLellan has made an excursion into a more serious type of drama. But it is only fair to state that such appeal as the play made last night was in large part due to the exceptional brilliant acting of at least five of its chief protagonists. One or two of the minor roles might have been better played, but making due allowance for the usual conditions of nervous exaggeration incident to a first night, it may be said with conviction that the acting of George Arliss, John Mason, Charles Cartwright, William B. Mack and the star herself, provided an ensemble such as is rarely excelled. "The Standard: (Source: The New York Times; May 3, 1905) 
"It is a piece far out of the common, and holds out the promise that in Mr. McLellan a new power has arisen." Daily Chronicle: (Source:The New York Times, May 3, 1905) "There hitherto were seven wonders of the world. The eighth is added ... that the author of The Belle of New York should be also the author of Leah Kleschna, the strongest piece of sheer stagecraft we have known from any source for years."
