In spite of hardly knowing any of these sports, I did a little better than I usually do with these quizzes (though two names escape me).
1. Troubled Waters. Shuffleboard. Hayden Danziger.
2. A Matter of Honor. Bullfighting. Luis Montolla (sp.).
3. Last Salute For The Commodore. Sailing. Wayne Taylor.
4. Any Old Port In A Storm. Scuba diving. Ric's fiancee.
5. Ransom For A Dead Man. Flying. Leslie Williams.
7. Death Lends A Hand (?). Golf. Lenore's tennis pro.
Just in the interest of keeping more people involved, I will point out that at least two of your answers, Grant, are incorrect, either partially or totally. I won't say which two until I give out the final answers. Good job, though, on your several correct responses!
