Full Text: "It is now almost a year since Wole Soyinka, the Nigerian playwright who was arrested by the Nigerian Government after he visited Biafra, was seen alive; and in spite of rumours that he had been killed or was seriously ill, General Gowon's regime has remained silent on his fate. Now Ama Ata Aidoo, a Ghanaian playwright, has written to General Gowon asking him to break the silence. Miss Aidoo, who decided to write the letter because she felt an official explanation was needed, met Soyinka some time ago. 'I don't know whether he will answer the letter or whether he will even get it,' she says. She has addressed her letter through the Nigerian High Commission in London. 'But I felt it should be written. People should not be allowed to forget Wole Soyinka's disappearance.' If General Gowon is worried about federal Nigeria's reputation for justice, he would do well to clear up this serious matter."
