The Impossibles

FBI Agent Kenneth Malone is back with another case; first, late-model cars began driving themselves away, then, valuables began vanishing from locked rooms. The issue he faces is that the thief seems to have the ability to make himself invisible.
The Impossibles is the second in a series including Brain Twister and Supermind written by the duo of Laurence Mark Janifer and Randall Philip Garrett under the pseudonym Mark Phillips.
