Order of Dillman & Masefield Books

George Porter Dillman and Genevieve Masefield serve as the central characters in a compelling historical mystery series penned by British author Conrad Allen (writing under his real name Keith Miles). These maritime mysteries are alternatively referred to as the Shipboard Mysteries or Ocean Liner Mysteries series. The detective duo operates as private investigators specializing in cases aboard ocean-going vessels during the Turn of the Century era.

The Dillman & Masefield series launched in 1999 when Conrad Allen published Murder on the Lusitania, introducing readers to this unique detective partnership. The maritime mystery collection spanned eight books total, reaching its conclusion in 2007 with Murder on the Celtic. The novels follow both publication and chronological order, creating a seamless reading experience for fans who wish to follow the characters' adventures sequentially.
