When June's mother asked Miriam at breakfast on what brought her to Singapore, she explained that her father got a job at the Harbour Board and the family came over to Singapore with him. The Singapore Harbour Board is the predecessor to the Port of Singapore Authority, or known as the PSA.
When Helen from the nightclub came to inform Dennis at his house on the MPAJA (Malayan People's Anti-Japanese Army) not giving up on him, it emerged that she is actually a spy for the MPAJA, though she explained that she was only passing information.
June at one time reminding her cousin Dennis to get their boss Mr. Da Silva to get his British contacts not to do anything stupid in regarding the case of Miriam, she used the word 'ang moh'. It literally means 'red-haired' from the Hokkien dialect, and it tends to refer to white people, and in this context, the British. It might had been viewed as a racist term to some, but it is still a widely-used term at least in the Singaporean context.
