On a lonely heath in northern Scotland they recovered the body of the third agent sent to complete a tricky mission. He had died from bubonic plague. Somewhere on the moors was a half-crazed scientific genius who could kill millions, and it was Helm's job to get him, with the help of a beautiful American operative and a deadly Russian one. PRAISE FOR DONALD HAMILTON “Helm is a genuinely tough and tough-minded protagonist... your reading diet lacks essential vitamins if you overlook him." NEW YORK TIMES “The top-ranking American secret agent fare. Good writing, slick plotting and stimulating characters." BOOK WEEK “Matt Helm is as credible a man of violence as has ever figured in the fiction of intrigue." NEW YORK SUNDAY TIMES
