. . . so is fool, an apt designation for Matt Erridge in this one as his shipboard romance turns as treacherous as hurricane surf. Meet the Grantland clan; Grandpa who rules with money and power and has a passion for improving the family bloodline: Mom, his daughter, who loves raw, bloody meat and hunting dogs and finally ""Spook,"" the lovely grandaughter, intent on hiding a murderous stowaway. The stowaway turns out to be a lost relative bent on erasing Gramps and Mum and it all ties in with a Nazi past and one of Grandpa's stock-improving deals. Kill Is a Four-Letter Word. . . so is bore.
