Murder on the Leviathan
Boris Akunin
 The novel is set in 1878. The story opens with the murder in Paris of Lord Littleby, all seven of his servants and two children of servants. All were poisoned except for Littleby, who was bludgeoned with an ancient Indian artifact, a golden statuette of Shiva, which belonged to Lord Littleby and was stolen from his room, along with an old Indian shawl. French detective Gustave Gauche, in charge of the investigation, boards the passenger ship "Leviathan". Gauche knows that the murderer must be one of the first-class passengers, because one of the special golden badges for the ship's first-class passengers was left in Littleby's room. Among the suspects are a Japanese army officer, an addled English aristocrat, a married Swiss woman, and a clever young Russian diplomat on his way to his new post in Japan. The diplomat is Erast Fandorin, the master detective, who shoots down each of the ineffectual Gauche's incorrect conclusions, and in the end takes it on himself to find the murderer.
