Ali is a police officer at Scotland Yard (the headquarters of the Metropolitan Police in the British capital of London). He was born in Lahore, Pakistan, and later married a British woman and had two children. After the London serial bombings in July 2005, Ali was ordered to investigate a related suspect. The work did not go smoothly. At the same time, as a Muslim, although he had worked at Scotland Yard for many years, he was also looked at strangely by his colleagues because of the bombings. Although the truth was finally revealed, the discrimination he suffered during the period and people's fear of the bombings still made him difficult to let go for a long time.
