Mission of Murder — Robert Charles

The tranquillizer drug Ameytheline was considered so safe that it was even prescribed for children, but it had deadly after effects. There was an antidote, but it existed only in the hands of a callous blackmailer who held the British Government to ransom. One of the faceless men of Whitehall revealed the facts to his most ruthless agent. And Simon Larren quietly left for Greece to steal the antidote and eliminate the man who held the lives of thousands in his hands.
