ORIANA in Crime fiction

"As the Passengers join ORIANA in Southampton they are hoping to leave troubles behind them for the peace tranquility and the unexpected delights of a summer cruise.
Not are on board for pleasure. There are those who seek revenge, hide a guilty secret or are escaping from an adulterous past. Others are mere opportunists

As the Captain steers a smooth course towards the warm waters of the Mediterranean, the passengers start to relax and romance begins to flourish
Then Murder strikes......" 
The above is the  interesting and somewhat fanciful synopsis of  The Cruise: A Novel of Murder & Romance which was published in 1995 offers "an a tale of consequences full of mystery and passion" which was set on board ORIANA.
The book written by no less than 14 authors among  them Bernard Cornwell, famed for his Sharpe series of novels, was the brainchild of the Dyslexia Institute who would receive a donation from each copy sold.
It also marks something of an usual use for a cruise liner while the great ocean liners of the past often may have played host to the odd murder mystery and even Britain's' most famous Secret agent 007 abseiling  down the side of the original QUEEN ELIZABETH it is a rarity, some might say mercifully, for a modern liner to play host this kind of fiction.
Having enjoy several cruises on board I can not help but be puzzled by how the authors envisioned such a fiendish plot within ORIANA's opulence.
