When DS Mark Pemberton embarks on a cruise to the Arctic Circle he's very much off duty. He simply wants to experience the spectacle of the Midnight Sun and the splendour of the glaciers and fjords. Then a man is found stabbed in a locked cabin and the captain turns to Pemberton - can he assist in investigating the death without alarming the other passengers? It's a fraught situation; with the liner still at sea, the killer must still be on board, and there is no way of knowing if he or she will strike again
