the Nawab´s last years

What do we know about the Nawab´s last years?

After Olivia´s miscarriage, the Nawab takes on her (p.157, ll.25-26). He buys a house in the mountain for her (p.158, ll.7-9). The Nawab one time comes to England, more precisely to London (p.158, l.5). There he meets Harry and his friend Ferdie, with whom Harry lives together now (p.158, ll. 1-3). The Nawab has changed a lot (p.158, ll.4-5), not only he himself had changed, but also his circumstances (p.158, l.4). He no longer lived at Claridges, because he had no money for this (p.158, ll.5-6). Thus his situation hasn´t become better, but worse.
