Another in the series of mystery-adventures about two independent ronin--Zenta and Matsuzo--who try to defend the right in feudal Japan. A third young ronin, Kajiro, takes center stage here, having been sent as a spy to an island fortress. Out of condition from too little exercise and too much drink, Kajiro finds himself mistaken for the famous Zenta and expected to clear the island of the ""ogres"" who have been terrorizing the people there. He also becomes the defender of young lady Yuri, whose cat leads her into several dangerous escapades. While Kajiro's health and reflexes improve, Zenta himself is recovering in the castle and trying to discover who is behind an attempt to rescue the mad Lord being held there. Sixteenth-century politics mix with lively dialogue, an intriguing setting, swordplay, and several romances. A good light read for mystery lovers.
