Literary World: "So much of the interest depends on the surprises in the plot, that we will not even give an outline of the story, but only say that it holds several absorbing situations."
Public Opinion: "A good story.... The mystery and agony preceding the discovery is drawn in just the right shades. There was danger of overdoing it, but the author was not to be entrapped.... There are surprises to the end."
Chicago Times-Herald: "There is such power of analysis, of description, and of imagination, that one feels sure that he has to deal here with the ebullition of an uncommon mind."
Saturday Review (London): "He tells his tale in so brisk and plausible a fashion that belief comes easily."
Graphic (London): "Has stronger motive for a novel of romantic and sensational adventure than is at all usual, and to the very great advantage of an otherwise exciting and well-constructed story."
