George's Secret

Betsy, a retired schoolteacher, is on a once-in-a-lifetime cruise in the Galapagos Islands. But not all Betsy's ship-mates are what they seem.

Betsy sees and hears some unlikely things. One person insists on collecting things, although to remove any item from the Galapagos Park is against the law. When the group visits George, the oldest living tortoise at the Darwin Research Station, Betsy sees one of her fellow tourists wiping a tortoise's mouth. Then one of Betsy's companions is abducted. The police become involved, and everyone is a suspect.

Mickey is the group's co-ordinator. He and Betsy seem to be on the edge of a romantic episode, when a volcano erupts and the traveller's yacht has to flee. Two of the small group die before they can reach the mainland. Mickey hatches a plan to catch the killer, and Betsy agrees to help, but she soon finds herself in a deadly struggle to survive.
