Death Duty [EPUB ebook] 

It’s a mystery to his colleagues how Jack Mowgley reached the rank of Detective Inspector. Or how he came to be in charge of a major intercontinental ferryport. Some reckon the eccentric detective had something juicy on those above him, particularly Chief Superintendent 'Gloria’ Mundy. In the first Mowgley Mystery, the resolutely unreconstructed, unredeemable and unapologetically out-of-date policeman learns that a passenger has gone missing on a ferry crossing to Cherbourg.
