尾梢

尾 = 尸 + 毛 : Willy Walrus (w) knows that there is a ghost (尸) in the Eiffel Tower (ei3), but he cannot see it, so he set up a trap: he put a lot of sticky hair (毛) everywhere, and eventually the hair stuck to the ghost's tail (尾). Now that Willy Walrus can see where the ghost is he is able to drive it out.

梢 = 木 + 肖 : Sherlock Holmes (sh) set up a Christmas Tree (木) in front of the aorta (ao1). Because he lacks a star for the top of the tree (梢) he asks the little prince (肖) to chip in and climb to the top of the tree.
