Sharp Rise in Crime — John Creasey

A somewhat incredible deception is planned so as to try and put an end to corruption that is undermining the very fabric of society and to deal with vice crimes that appear to reach the highest levels. Scotland Yard announces that one of its best detectives, Roger West, is dead. The story is credible, as West has recently been the target of would-be assassins. Meanwhile, West does his best to penetrate circles in which the conspirators operate.
