The Hector Lee court case revealed the reasons why Helen Ho and Yvonne Ho were secretly monitored :
Lieut. Murakami was rounding up suspects in the New Territories between Sheung Shui, Taipo, Shutaukok and Yim Tin by surprise raids from land, and sea. Witness went with one of these armed expeditions as he could speak Hakka.
Witness said that Colonel Noma's girl friend picked up a piece of paper at the border. The message was from Helen Ho to Father Patrick Bourke and referred to half a dozen tubes of shaving cream and razor blades. Witness was told to translate the message.
Accused was assigned to investigate the movements of Miss Yvonne Ho, who was working at the Japanese Foreign Office.
