Discovery on the Duoro

Learn About the Book

Picture
She expected to relax on her river cruise through Portugal. She didn’t expect threats from the mafia.

Adelle didn’t expect her retirement to be boring. But when a valuable port goes missing, and her friend invites her to launch a new career to find it, the born people-pleaser jumps at the chance to demonstrate her skills. But when the mafia becomes involved, she loses her nerve.
Eager to prove her capabilities, Adelle struggles to manage her fears without making waves. And with threats rising faster than the ship in the river lock, she’s terrified she’s drowning in dangerous waters.
​
Will Adelle discover the missing port before her new career sinks?

Discovery on the Duoro is the exciting fourth book in the River Cruise Cozies mystery series. If you like adventures abroad, quirky characters, and solving mysteries, then you’ll love Cheryl Dougan’s newest river journey.
