Dr Palfrey Series by John Creasey

A megalomaniac stumbles across a curious chemical in certain deposits of impure uranium which results in instant death as it is passed from one person to the other. Can Dr. Stanilaus Palfrey defeat Anak’s plan and can Banister (one ‘n’) and Rita be reconciled as she emerges from her murderous sleep? And just how should the United Nations react in the face of this blatant attempt to dominate?

A plague appears that kills thousands; is it being controlled by evil men?

Silence reigns; there is no noise that cannot be excluded. The daily roar from factories, aircraft, and explosions can all be insulated against. Humans can also be protected from the ravages of radioactive contamination. But there is a price; the loss of man's freedom. This is the dilemma that Dr. Palfrey must solve. Can he do it? The reader is the judge.
