Some people think that Hawaii is a paradise, but Monk knows that, like dirt, danger lies everywhere. Monk suspects that the death of a rich tourist, Helen Gruber, who took a blow on the head from a coconut, is anything but an accident. His assistant, Natalie, isn't thrilled about Monk's new assignment - it was bad enough him following her on vacation and now it looks as though the holiday is well and truly over. However, finding the killer proves harder than initially thought - and that's without the added complications of geckos and unsynchronised ceiling fans!
