A student in the “Science Sixth” at Tony’s school, Robson never appears directly in the novel, but is a significant reference point for Tony and his friends after he commits suicide, having gotten his girlfriend pregnant. The boys view his suicide as less a tragic event than an opportunity for them to speculate endlessly and abstractly on his reasons and motives. For Tony, Robson’s suicide is also a counterpoint to Adrian’s, since he understands the latter as admirably well-reasoned and the former as desperate and weak: much of the novel will work to complicate and challenge that view.
