Super-science plus Cold War on the astral plane--an unlikely combination that adds up to diverting, but never convincing, suspense. British psychic George Kenrick has been using his astral, Direct Influence (DI) powers to help British Intelligence persuade Soviet sub commander Selyeznov to defect and give them the lowdown on the new Soviet antisubmarine device ""Kingfisher""--a sonar/laser that can beam a laser-soundwave over long distances, giving off a high-pitched shriek that shakes the enemy sub to pieces. But the Soviets have their own psychic team, led by overweight Captain Gianna, a white-faced lady with the power to invade men's minds with lubricious visions. And so, as Kenrick is crossing the North Pole in an airliner, Gianna affects the plane's magnetic compass, leading the aircraft into Soviet territory: Kenrick is captured, given a psychic-wise lobotomy, and returned to Britain as a semi-zombie! Then: enter American photographer Pete Harvester, just arrived in London with his wife Judy to shoot some PR stills of a new film in production, who happens to be the greatest (but retired, because of Judy's uneasiness) psychic in the Western world. Despite Judy's opposition, British Intelligence ropes Pete in to replace Kenrick and use DI on Selyeznov, whose sub is passing through the Channel; and Pete thus becomes a victim of Soviet psychic Gianna's evil: she torments him with visions of a naked teenage sexpot, then makes him think he's committed a murder, then locks him out of his own body! All ends happily, however, thanks to wife Judy's astral intervention. An outrageously farfetched hodgepodge--but tightly, stylishly told.
