Urgh... I'm at my wits' end in Chapter One. Got the book, reading/playing it, been to the Beach, Lighthouse, Cove, Cliff, got the bottle and bit of sail from the wreck (should be all the obvious things, at least), three items from the Cove screen, the shield is clean - but I just can't find a way to light the beacon. I'm just running around the island like a lab mouse on speed...
