Pick Your Poison is het vijfde deel in een avonturenreeks over de ondernemende Rudy Redfort. Alle delen zijn los van elkaar te lezen.

Wisecracking, code-cracking girl detective Ruby Redfort gets an unexpected taste of the action in her fifth fast-paced adventure.Ruby Redfort: You can count on her if you're between a rock and a hard place. A bite from a poisonous snake? Pass me the antivenom. Need someone to take the fall? You don't even have to ask. Stay one step ahead of trouble? Not so easy. There are always snakes to look out for, but they aren't half as poisonous as the rumors floating around Twinford. It's a lot to chew over. Will Ruby pull through in one piece? When trouble's out to get you and being smart is not enough, do you run like crazy, or is it time to brush up on your martial arts?
