Three Brummie hotshots

Three different stories but each with a link to England's second city, Birmingham.
We have Dave, whose life after conscription in the army took him to Japan, Korea and Germany. Later he was paid to kill a high ranking Russian by a woman whose family he had destroyed.
Then we have Charley, whose interest and aptitude in diamonds took him to northern Europe and eventually rich pickings in the Far East and Singapore in particular.
Then we have Lionel whose police work led to various overseas trips including North America, Mexico and Canada.
One other factor that has a common theme is that they are all hot shots when it comes to shooting...
