Marple is extremely proud when she is appointed to the board of trustees of a merchant marine training vessel whose mission is to rehabilitate young criminals. As in all of her endeavors, Miss Marple intends to take an active role in the job and even shows up to the board meeting dressed in naval blues. When a fellow trustee is poisoned just prior to his making some kind of revelation, Miss Marple decides to use her position to spend time on the ship. This upsets the vessel's fragile social network as she dispossesses blustering Captain Rhumstone from his quarters. When two ship's officers are later found murdered also, Miss Marple enlists help from her friend Jim Stringer and Inspector Craddock to expose the murderer.匕首横着向前划过去，张曜砍开一个正扑向他的兽人，身体随即又向旁侧弯下，躲开后边兽人伸过来的一爪子，右脚抬起，猛力向后一踹，踹上一个正要偷袭他的兽人肚皮之上。张曜感觉他这一脚过去，能清楚感受到兽人的肌肉，果然很是结实，硬邦邦的，根本就像是踹在了钢铁上一样。若换做平时，张曜很自信自己这一脚过去，能把个正常体型的男人立即踹倒在地上，但是现在，那个刚被他用脚踹中的兽人，只是身体向后倾了倾，接着又毫无什么痛感的继续追上自己。
