Sometimes the best research happens when you don’t even know you’re doing it, when you’re just going through your day-to-day life. But it can take a long, long time for it to filter into the fiction.
Tolkien’s work has very little of interest in it to a reader of literature, in my opinion. When I think of literature—Dickens, George Eliot, Joseph Conrad—the great novelists found their subject matter in human nature, emotion, in the ways we relate to each other. If that’s what Tolkien’s up to, he’s left out half of it. The books are wholly male-oriented. The entire question of sexual relationships is omitted.
Set in Cairo, the novel tells the story of Bassam, a man lost inside a "spiderweb of emotional frustration and failure." Oscillating between the present, the past and the future, it explicitly describes sexual acts.
