From THE PALL MALL GAZETTE.—'The main interest of the book, which is very strong indeed, begins when Vincent returns, when Harold Caffyn discovers the secret, when every page threatens to bring down doom on the head of the miserable Mark. Will he confess? Will he drown himself? Will Vincent denounce him? Will Caffyn inform on him? Will his wife abandon him?—we ask eagerly as we read, and cannot cease reading till the puzzle is solved in a series of exciting situations.'
