The luxury liner, RMS Aquitania, embodies all that is gracious and refined in a world by gripped crisis and doubt. But the elegant atmosphere on board is charged with tension. Civility remains - but how long will the peace hold when people start to die? After months abroad, Rowland Sinclair and his companions begin their journey home on the ship. They dine with a suffragette, a Bishop and a retired World Prophet. The Church encounters less orthodox religion in the Aquitania's chandeliered ballroom, where men of God rub shoulders with mystics in dinner suits. But soon the bodies pile up, and Rowland unwittingly finds himself at the centre of a murder investigation again. Can he unravel the mystery and stop these heinous crimes before he and his friends become victims themselves?
