Murder on the Oceanic - Edward Marston

Southampton, 1910. When the Oceanic sets sail its ultimate destination is New York. But it must make one very important stop first: at Cherbourg, to pick up internationally renowned financier and art collector J. P. Morgan, fresh from a continental buying spree. George Dillman and Genevieve Masefield, the ship's detectives, are nervous about the presence of such an important passenger, not to mention his valuable cargo. After all, it is rare for a transatlantic voyage to pass without incident for the two sleuths. The everyday difficulties of managing passengers including a charming rake intent on causing mischief and a controversial painter travelling with his bohemian wife and his alluring French model, are brought to a pitch when a major art theft takes place and a throat is cut. Dillman and Masefield must draw upon all their experience to find the killer before it is too late.
