Introduction to the thriller books of Michael Gilbert

While Michael Gilbert wrote across multiple crime and thriller subgenres, his espionage books, particularly Game Without Rules showcase his skill at blending realism, dry wit, and high-stakes intrigue. A former lawyer, Gilbert brought a sharp, analytical mind to his storytelling, offering spy fiction fans meticulously constructed plots filled with betrayal, deception, and the quiet, unglamorous reality of intelligence work.

Michael Gilbert was a very good crime writer, famous for a series of acclaimed detective novels over a period of 50 years (Smallbone Deceased, Death Has Deep Roots, Death in Captivity). The reason he is here, though, is that he is also responsible for the two best collections of short spy stories I’ve ever read – the only short-form writing that eclipses Brian Garfield’s Charlie Dark stories. Gilbert’s characters are the highly eccentric but deadly killers Mr Calder and Mr Behrens who take on the jobs that the main agencies will not touch..

Key Spy Novels by Michael Gilbert

Gilbert’s espionage fiction is known for its tightly controlled tension, moral ambiguity, and understated British style. Here’s a guide to his most notable contributions to the genre:

1. Game Without Rules (1967)

Miss Marple meets John le Carré in these linked short stories of espionage and mystery, with two middle-aged British Intelligence agents (and a dog!) as sleuths.

  • A collection of short stories featuring two veteran British intelligence operatives, Daniel Calder and Samuel Behrens, who use ruthless, often unorthodox methods to eliminate threats to national security. Game Without Rules is a hidden gem of spy fiction, showcasing Gilbert’s mastery of the form.
    Themes: Cold War morality, pragmatism, and the real cost of espionage.

2. The Queen Against Karl Mullen (1967)

  • A legal thriller with strong espionage elements, featuring an MI5 agent caught in a web of deceit that puts him at odds with his own government.
    Themes: Justice, manipulation, and political intrigue.

3. Death in Captivity (1952)
