Dillman & Masefield Books in Order

How to Read the Dillman & Masefield Series

The Dillman & Masefield series—also commonly referred to as the Ocean Liner Mysteries—was written by Welsh historical mystery novelist Keith Miles under the pen name Conrad Allen. In recent years, these books have also been reissued under Miles's better-known pseudonym, Edward Marston. Because the characters' personal and professional relationships develop continuously from book to book, the recommended reading path is the publication order, which also matches the internal chronological timeline of the stories.

You should start the series with the first novel, Murder on the Lusitania, which introduces the protagonists, establishes their undercover role as shipboard detectives, and initiates their partnership.
