Query: The epitome of hard-boiled

I've been a fan of Hammet for quite some time and I really like the Thin Man and the Maltese Falcon but my favorite of his is the Continental Op. Here we have a hero whose name we are never told! He is the epitome of hard-boiled, a man who can dish it out as well as he can take it.The Big Knockover is a nice collection of ten perfect short stories. The first, The Gutting of Couffignal, is the story of a small village under seige and has a neat twist. Fly Paper will keep you guessing.
