The Human Factor

Castle is the ultimate intelligence man...reliable, trustworthy, and nearing the end of a seemingly placid career in secret service. When a leak is traced to his department, it is natural that his assistant, the flamboyant Davis, should come under suspicion. The head of the service proceeds to have Davis quietly eliminated. But there is more to Castle than what he appears. His black South African wife and her son claim his fierce, intense love. A love so fulfilling brings obligations - the human factor. In security work, the necessity of caring brings risks. --Book jacket.
