Murder on the Celtic in Bloomington, MN

New York, 1910. George Dillman and Genevieve Masefield have crossed the Atlantic Ocean numerous times in their capacity as ship's detectives. On those crossings they've had the pleasure, and in some cases the trouble, of sailing with very famous passengers. Dukes. Duchesses. Artists. Actors. Musicians. Royalty. But few names have quite the level of fame and fortune as their fellow traveller Sir Arthur Conan Doyle.
Now aboard the Celtic, Dillman and Masefield have a particular stolen book to recover and an elusive fugitive to apprehend, but will the famous writer help or hinder them? Previously published under the name Conrad Allen, the Ocean Liner series is making waves with a new generation of readers.
