A Gillard and Langley Mystery - Patrick Gillard and Ingrid Langley, late of MI5 and now working as consultants for SOCA, are called in to investigate when a policemans horribly mutilated body is found with the initials R.K. carved on his torso. At the same time, DCI James Carrick asks them to make enquiries on a private matter: he has discovered that his father, Robert Kennedy, whom he thought long dead, is not only alive but a criminal. Can there be a connection between the two cases?
