Another of veteran Eberhart's meandering plots--with characters who stay dim despite all the trappings piled on them. Among the passengers on the yacht Felice, Monty Montgomery's grandiose new polished-mahogany toy: Monty's maybe-future wife Sue Gates; his maybe-past-mistress Celia Hadley; Sue's hard-drinking Aunt Addie, with old acquaintance Stan Brooke, a Navy officer; plus the Felice's previous owner, rich and feeble Sam Wiley. And the one-man crew is sly, competent Juan. Then, as the yacht wallows around in the fog, Monty is pushed overboard and rescued. Juan is eventually found murdered. There's a temporary rescue by the Coast Guard--but Monty is determined to find out who pushed him. His shipmates long for dry land. And all but Eberhart's most blindly faithful fans will long for deliverance from the uncommon tedium here.
