This is a classic novel; it is psychological, it is mystical, it is an adventure novel, and it is a love story. But it is also a modern novel, even post-modern.
A nonagenarian, Bruno, has been sitting in his room for months. He contemplates his stamp collection and thinks about his life, which now seems like a dream to him. He also reads treatises about spiders, with which he is beginning to resemble - God himself is a spider, with his thin and golden thread we are constantly struggling to hold on, but most of the time we escape - so all the other characters get caught in his web: the son-in-law, the son, the caregiver, the maid.
These characters - beautifully described, are true symbols: the artist, the mediocre, the madman, the escaped - somehow seek - in any way - fulfillment. And, together with the old man/spider, each has his own peculiarity: one has mystical ecstasies and believes he is God, another has three loves at the same time, there is even the beginning of a ménage-à-trois; two are mourning and a cook has the name Odette from Proust.
Obviously, everything ends well, like in Shakespeare, and in the end, what remains?
