Consequently, the ubiquitous Japanese became the source of 'spy fever', as rumours circulated through the peninsula. The British colonial authorities, over-sensitive to possible diplomatic repercussions from action against nationals of a country still, nominally at least, friendly, obtained sufficient information to substantiate some of the suspicions of Japanese espionage, but generally preferred quietly to deport suspected agents. Nevertheless, occasionally cases did
