Quiller a fascinating character. His creator describes him as "In his forties, he is as fit as an alley cat and his whole makeup is tense, edgy and bitten-eared." Unlike James Bond, he doesn't drink or smoke, nor does he engage in relentless womanizing. In fact, Quiller is quite respectful of women. In the words of Adam Hall...
Nor is he macho, and this may explain why more than half the people who write me are women. In Murmansk, where Liz is applying Tiger Balm to our bruised and bloodied espion, she asks him if he doesn't find it irksome to have his wounds licked for him by a mere woman. He scarcely understands her. "Where else would a man go, but to the earth mother?"And while Quiller had few possessions and little wealth, anything he had was to go to a shelter for battered women should he die on a mission. This was a cause close to the author's heart as well. According to Elleston Trevor's obitituary, "Late in life he took up the cause of battered women, campaigned vigorously for that, and was generous with money."
Quiller hardly every uses a gun, preferring to use his wits or martial arts skills. (The author of the series was well-versed in both Shotokan Karate and Aikido.) Quiller is also the type of individual who relies on herbs and traditional Asian massage to deal with injury and illness. At one point he even mentions he once traveled to Tibet to meditate.
Often referring to himself as a ferret, Quiller had an affinity for animals. To again quote Adam Hall...
