First televised in Britain, where it was made, on Saturday, November 2nd, 1963.
The Scottish actor Andrew Keir plays Sir Roger Casement, a real-life person, in this episode. Casement was a prominent consular official in the British government, which knighted him after he had been instrumental in exposing abuses of native labour in parts of Africa and South America. He retired from the consular service in 1913. An Ulster Protestant, he devoted the rest of his life to the cause of Irish independence, in defiance of his former governmental colleagues; he was involved in secret activities in Germany during the First World War and was executed by the British at age 52 in 1916. His body is now buried in Ireland, according to his last wishes - these wishes, however, were not carried out until 1965.
