Five Passengers from Lisbon

From the jacket: "Boarding the ship was like entering a dream for Marcia Colfax. At her side was the man she loved; awaiting them was a long delayed happiness. But now a bloodstained knife has slashed her plans to bits. Now her dream has become a nightmare. One man is dead, a knife buried deep in his back. Another has met an even more gruesome end. Now her voyage to happiness has become a race against death as the murderer readies to strike again."

Shortly after the end of the war, an American hospital ship rescues passengers and crew from a sinking Argentina-bound freighter. It's soon discovered that one of the group has been murdered, apparently by one of his own companions. After the second of the group is found dead, fear spreads throughout the ship, as do rumors that Nazi diehards lie among the rescued.
