An Antarctic Mystery

Wealthy American Jeorling, who has entertained himself with private studies of the wildlife on the Kerguelen islands and is now looking for a passage back to the USA. The Halbrane is one of the first ships to arrive at Kerguelen, and its captain Len Guy somewhat reluctantly agrees to have Jeorling as a passenger.

Underway they meet a stray iceberg with a dead body on it, which turns out to be a sailor from the Jane. A note found with him indicates that he and several others including the Jane's captain William Guy had survived an assassination attempt and are still alive.
