Selwyn Selwyn-Clarke is still being held in a Kempeitai cell in the Supreme Court:
Day and night he lay on the filthy concrete floor of his 6'/2x5 feet cell wearing nothing but shirt and trousers and crawled over by cockroaches from a nearby latrine - conditions particularly revolting to a hygiene loving medical man and at their worst in the damp heat of a Hong Kong summer. In this loathsome spot, his legs painfully swollen with beriberi, he passed his fiftieth birthday on 17 December 1943.
