South from the Seychelles

In the sixteenth book in the Wallace Boys series, Nigel and Bruce are aboard their yacht the Silver Spray cruising the Islands of the Seychelles in the Indian Ocean. Out of the blue, they are invited by Barry Jones – readers may remember him in The Sands of the Skeleton Coast and Trouble in Tristan – to help with a slight problem.

His motor yacht, the St Valery II, has been hired by a group of rather sinister individuals to visit the remote Kerguelen Islands in the South Indian Ocean. He needs the boys' help. It promises to be a hairy ride to one of the most inhospitable places on earth, also called the Islands of Desolation. They also visit the even more remote, desolate Heard Island.

The destination is Nazi gold!
