Cab is ex military special services now working in close protection for high net worth individuals. He is noble - a Byronic hero, prefers solitude, dreams of living off grid in the wilds of Wales, instead of working in urban environments. He has a dark sexuality as well as craving tenderness. He considers himself to be irreparably damaged psychologically but also has a very strong moral code. None the less he can’t help but find the most satisfying sexual pleasure from consensual non consent play with the wife of his best friend who has found her most satisfying sexual pleasure from being restrained and forced by him and experiencing his capacity for being highly threatening and dangerous. The flip side of this is his enormous protectiveness of her in real life.
