After moving to Bangkok in 1956, Jacqueline learnt Thai as she was punted around the canals (‘klongs’) of the city by her gardener in a canoe. She would take piles of typewriter paper with her to sketch local people at work.

Whilst visiting New York she showed these to Margaret McElderry, a children’s book editor at Harcourt Brace, and the response was positive. She was advised to write a story from what she saw around her in Thailand, and the result was her first children’s book, Nu Dang and His Kite.

Ayer wrote and illustrated five of her own books, four of which gave insight into 1960s Thailand to US and UK audiences, while the fifth was set in Hong Kong.
