From the 15-minute summary · Key idea 1
An Old Letter Sends Three Men West
The story begins with a surprise visit. On the porch after dinner, Steve Rogers tells the boys about a rainy morning in the attic of his parents' house in Gloucester, Massachusetts. Behind a pile of old things he finds a small trunk. Inside is an old pocketbook, and inside the pocketbook is a folded paper.
It was written on March 20, 1816, and signed Sol Rogers, his grandfather from about six generations back. The writer has buried a man named Jim and fears he is falling sick too. He has hidden about a hundred pounds of a metal that looks like silver. Jim tried it with aqua fortis, an old name for nitric acid, and it did not dissolve at all.

What is The Hunniwell Boys and the Platinum Mystery about?
Two brothers from Maine and a Secret Service friend fly an electric plane to Molokai to follow an 1816 map to hidden platinum. On the island they face thieves, a kidnapping, fog, tides and a rescue at sea.
Who are Bill and Gordon Hunniwell?
They are brothers from Skowhegan, Maine, who built and fly the Albatross. Bill is the steady pilot and mechanic, and Gordon is the quick, funny one who often comes up with the daring idea.
What is the Albatross in the book?
It is the brothers' light airplane, driven by electric motors and powered by copper cells invented by their friends. A second propeller lifts it straight up, so it can take off in tiny spaces and fly almost silently.
