On a transatlantic cruise, three elderly gentlemen have the adventure of a lifetime
When the captain of the SS Sunderland sees the three grey-haired passengers, he does not expect them to cause any trouble. He is mistaken. If he knew how much trouble they will cause, he'd likely leap over the railing and swim for shore. Carruthers, Simpson, and Briggs are three of the most dangerous men in the world. Founders of the British Mystery Writers Club, they were once well-known authors of detective fiction. But recently, their business has shifted from writing about murders to committing them.
As members of the Murder League, the men are willing to kill any man on earth for the price of $1,000, and kill him in style. The Sunderland is in for a very blood crossing, and there will be plenty of work for the Murder League.
