The detective's guide to ocean travel / Nicki Greenberg.

For as long as she can remember, Pepper Stark has wanted one thing: to join her father, the Captain, aboard the magnificent RMS Aquitania on a voyage to New York. She has never been allowed to set foot on her father's ship, until now. From the decadent food to the star-studded passenger list, travelling First Class on Aquitania is every bit as glamorous as Pepper had imagined. And most dazzling of all is American stage sensation Perdita West, wearing the world-famous Saffron Diamond around her neck. When the priceless jewel disappears mid-voyage, Pepper unexpectedly finds herself entangled in the crime. With the Captain's reputation at stake, Pepper and her new friends set out to solve the mystery. But finding a missing diamond isn't so easy on Aquitania, where everyone has something to hide.
