When I visited Arthur C Clarke's grave a couple of weeks back I found a Japanese book placed by the headstone (see post 05.08.13). I figured it was most likely an Arthur C Clarke book but had no idea which. Well, as I had our Japanese friends Hitomi and Katsuya over I asked them if they could make anything out from the random page it had fallen open on.
They could tell me it featured a Professor Kazan, a Doctor Keith, someone called Snowy and 'dolphin language'. That was enough for me to find out that the book in question is Dolphin Island.
