The Final Mas Arai Mystery After surviving the atomic bomb in 1945, Mas Arai returned to Hiroshima only once, fifty years ago, to find himself a bride. Now the retired, 86-year-old Los Angeles gardener is going back out of obligation, to deliver his best friend Haruo's ashes to Haruo's sister. As soon as he arrives at her nursing home on a small island off Hiroshima, he becomes embroiled in the mysterious death of a teenage boy who was about the same age Mas was when the Bomb fell. Mas knows he's too old to be chasing murderer suspects, and being back in Hiroshima brings up terrifying memories, but he simply cannot ignore his curiosity and desire for justice. Mas's keen eye, quiet determination, and focused moral compass lead him on a quest through the past-and into the future-in a journey that he never expected.
