Bruce was a manly romantic who loved thrillers: "A Civil Man" exemplifies the tight action, with heart, that moved him. He was a World War II expert, and knew the European Theatre particularly well, as reflected in his handling of both the background material and weaponry in his action-packed novel. He loved spy novels and intrigue, and learned all he could about the OSS to add to the authenticity of this novel.
His theatre background and love of films (most of Steve McQueen's films and the great "LA Confidential") gave him a strong sense of dialogue and character, and a freedom to explore a wide array of characters.
His literary influences were mostly contemporary writers of a certain genre: the early works of Robert Crais, Robert North Patterson, and James Lee Brooks. He thought the book "Three Days of the Condor" to be nearly perfect.
His life was cut short, but "A Civll Man" will tell you a lot about Bruce's sensibilities: his sense of loyalty, family, fun, romanticism, and fascination about how adversity affects the human spirit.
As you will find in " A Civil Man", despite war, death, and injuries, we can all make a choice to retain our humanity.
