"An engrossing romance of the sturdy, wholesome sort, in which the action is never allowed to drag," (_St. Louis Globe-Democrat_) best describes this popular novel. "The Shadow of the Czar" is a stirring story of the romantic attachment of a dashing English officer for Princess Barbara, of the old Polish Principality of Czernova, and the conspiracy of the Duke of Bora, aided by Russia, to dispossess the Princess of her throne. It is not an historical novel--the author makes his own events after the manner of Anthony Hope, and the _Boston Herald_ is of the opinion that it "excels in interest Anthony Hope's best efforts." "Rarely do we find a story in which more happens, or in which the incidents present themselves with more suddenness and with greater surprise," says the _New York Sun_. "Mr. Carling has a surprising faculty of making it appear that things ought to have happened as he says they did, and as long as the book is being read he even succeeds in making it appear that they did happen so," says the _St. Louis Star_. "The Shadow of the Czar" fairly captivated two countries. In England the _Newcastle Daily Journal_ says it "transcends in interest 'The Prisoner of Zenda.'"
