To my knowledge, he (Wallace) worked at least 80 hours a week: coming to his desk every day. He lived in the Officers Mess and regarded himself as always on duty. On my arrival, I found that he had taken virtually no leave for six years. He had a knowledge of the Irish situation which was totally unique in the Headquarters and surpassed that even of most of the Intelligence Branch. As time progressed, he was not only the main briefer for the press, but also the adviser on Irish matters to the whole Headquarters and - because of his personal talents - contributed much creative thought to the Information Policy Unit. In order to do his job, he had constant and free access to information of the highest classification and extreme sensitivity.
