This second book after BrainTwister and prior to Supermind and tells the story around FBI agent Ken Malone.

Kenneth Malone lives in a world where psionic powers such as telepathy and teleportation exist. He must cope with them as well as an FBI Director who leaves Malone continually confused about what situation he is being asked to handle and what he is expected to do about it.

Kenneth Malone--sometimes known as Sir Kenneth of The Queen's Own FBI--had had problems with telepathic spies, and more than somewhat nutty telepathic counterspies. But the case of the Vanishing Delinquents was at least as bad....

The Impossibles is the second part of their ”Psi-Power series” and was first published as Out Like a Light in Analog, April/May/June 1960. The first story they wrote in the series was Brain Twister (first published as That Sweet Little Old Lady, published in the Sept./October 1959 edition of Analog Science Fiction and Science Fact. The last story is Supermind (first published as Occasion for Disaster in Analog, Nov/Dec 1960 and Jan/Feb 1961.

This series is one of the highlights of 1960s SF, and still highly recommended.
