In Biggles in the Orient, Tahil was a partner of Messrs. Tahil and Larapindi of Calcutta, a company of shippers and merchant's agents. Tahil and Larapindi imported goods from and represented many British firms in India, such as Charneys, a manufacturer of confectionery based in Britain. They had a large warehouse in the docks area of Calcutta and offices in many cities in Eastern India.
Biggles never met Tahil as by the time he arrived in India, Tahil had died from a snakebite on a golf course while playing a round with his partner Larapindi. Biggles later suggested this might have been a deliberate plot by Larapindi to get rid of his partner but this was never proven.
