One Bullet Too Many — Paul Bennett

Life in the Polish resort of Lake Cezar is idyllic until local crime lord Emil Provda starts a protection racket among the resort's businesses. Provda has picked the wrong battle; local hotel owner Stanislav is one of a group of five ex-mercenaries, and he gets together his old gang for one last fight, to close Provda's racket down. Their crusade brings them up against their toughest opponents yet. The odds against them rise with each battle until the final duel on a deserted island. Just when they think it's over, there's one bullet too many; but who is on the receiving end?
