he Young Kindaichi is back and better than ever! In this first of many cases, Kindaichi finds himself onboard a cruise ship in which the captain mysteriously disappears the day after a big party. A search of the ship finds nothing, except for little drops of blood on the light switch in the captain's room. Might it be a clue perhaps? You bet! When what looks to be a case of serious foul play unfolds, the ship's radio is found disabled-so much for contacting the authorities. So, far out at sea until they can reach land, it's up to Kindaichi and friends to find the killer - and stay alive! -- NTV (abstract from Dramawiki)
