Henry 'Sir Galahad' Oliver arrives at Waterloo in the London cold with no overcoat, sure the city is his to conquer. Later, when out of work and starving, he catches and eats a pigeon in Kensington Gardens. Together these scenes show racism being internalised as a fault in the self, and poverty stripping an immigrant's early swagger down to survival.
In this London, racism mostly works through courteous refusals rather than open hostility. The room turns out to be 'already taken', the job 'just filled', and a landlady's smile keeps a lodger at a distance. Because the English 'don't tell you to your face', the victim can never prove the exclusion. He has to learn to read absences, like doors that close softly, as the real signal.
Both the narrator and the characters speak a Trinidadian-inflected English. This removes the usual split where standard English frames the story and dialect is quoted as local colour. When the immigrant idiom narrates Bayswater, Marble Arch and the Harrow Road, it takes over the imperial capital's landmarks and gives them new meaning. Choosing the voice becomes an act of belonging that the characters cannot achieve socially.
The men survive through 'the hustle': borrowing, sharing rooms, dodging rent, and chasing women and small cons. This improvised mutual aid keeps them alive but traps them in a loop with no progress. Sunday-morning gatherings in his room give a feeling of community that covers each man's deeper solitude and aimlessness.
