exhaust on grass or foliage. None of the residents of the nearby estates reports any sightings of military units. The lawns and soft ground within the estate show no footmarks of athletic men or any signs of their equipment.
(4) The Political Dimension: Foreign Powers The scale of the Pangbourne Massacre, the number of victims and the daunting task of controlling a large group of children together suggest the deployment of resources that only a foreign power could muster. Many of the murdered parents held senior positions in professions that brought them into frequent contact with foreign governments. The possibility exists of an elaborate act of revenge for unpaid debts or âconsultancy fees.â
    Comment: exhaustive inquiries confirm that none of the victims was politically involved in any way. Their only contacts were with U.S. and EEC governments, and the latterâs willing collaboration in the police investigation rules out this possibility.
(5) International Terrorism Ballistics analysis of the spent bullets and the curious collection of weapons used point to the possible involvement of an international terrorist group, perhaps the IRA or a disaffected assassination squad of Libyan professionals. But the absence of any trace left by such a group, as well as the abduction of the children, rules out this option. However, the example of Patty Hearst suggests that one of the older children may have been brainwashed by a maverick group, perhaps a successor to the Baader-Meinhof gang, the French Action Directe, or the Italian Red Brigades. This remains an outside but remote possibility.
(6) Organized Crime At least two criminal gangs in the East End of London and one in Glasgow are capable of mounting the large-scale operation involved in the Pangbourne Massacre. The abduction of the children may be part of a mass kidnapping attempt that misfired. Alternatively, the massacre may have been a revenge killing by an international drug syndicate. But there is no suggestion that even one of the parents was involved in drug dealing, in the laundering of syndicate revenues through the London money markets, or in any other activities connected with organized crime.
(7) The Parents as Killers Could one or more parents have killed the others, and then committed suicide? Possible motives include sexual jealousy, professional rivalry or individual psychopathy. Could the appalled children, in a state of shock that has still not lifted, have then fled the estate, taking refuge in a remote property owned by one of the families? Curiously, for all their participation in group activities at the recreation club, the parents themselves did not mix socially, never invited each other into their homes, and seem to have known one another only as casual acquaintances. All the domestic staff agree that in the three years of the estateâs existence there was not a single example of marital infidelity between fellow residents, a remarkable tribute to the concepts of social engineering built into the estateâs design.
(8) The Domestic Staff Could disaffected members of the domestic staffâthe chauffeurs, housekeepers, cooks and tutorsâhave turned against their employers? All the servants on leave (one, an elderly gardener, died of a heart attack on hearing of the massacre) were repeatedly interrogated, and far from showing resentment they all seem to have sincerely admired their employers, and were clearly happy to work for them.
(9) Bizarre Theories There remain a few outlandish possibilities.
    (a) A unit of Soviet Spetnaz commandos, targeted on the residential quarters of the NATO headquarters staff at Northwood, received an incorrect war alert order and were parachuted by error into the Pangbourne estate during the night of June 24. They slaughtered the adult residents, assuming they were senior military personnel, then realized their error and abducted the children.
