Semi-retired, septagenarian, widowed Japanese-American gardener Mas Arai is plucked from his comfortable bachelor existence in Altadena, California by an urgent call for help from his daughter Mari in New York. The alternately reticent, prickly, humble, pushy Mas finds himself negotiating the crowds and climate of the Big Apple to come to the aid of Mari, her husband Lloyd, and his three month old gransdon Takeo. Before he can catch his breath, he finds a murdered man buried under a pile of trash in an empty garden pond. First his son-in-law is a suspect then his daughter is arrested and charged with the crime. His home put up as collateral and $10,000 charge on his new credit card for bail, he's determined to see his daughter set free.
In a complex if meandering plot, the narrative moves along quickly, pausing to introduce historical and cultural background including observations of the on-going effects of the forced relocation of Japanese-Americans at the start of WWII. A host of interesting characters, described as only a Kibei (born in America and educated in Japan) and survivor of Hiroshima like Mas Arai can do.
