With far less commercial intent, the device of Grand Hotel has been applied to a ship destined to become a Titanic as a few of the members aboard recapitulate their incomplete to unfulfilled lives through reveries of the past or ruminations on the present. They include Stephen Russell (he will be saved), a young man who after World War II has not altogether given up hopes of marrying the daughter of an immensely wealthy industrialist; a young couple; an old man who lost his wife to insanity long before she died; an attractive survivor of two marriages; and in particular one Jesuit Father Curion who not only has a vision of the tragedy to come but meditates on the three great ""mysteries of life""--birth, death and paradox. . . . Mr. Eustace tells his story in a grave and courteous fashion with religious implications and mystical fibrillations which give it a little more extension while not quite defining its audience--perhaps an older one?
