What to read after Summary of Howard Blum's The Spy Who Knew Too Much?

Please note: This is a companion version & not the original book. Sample Book Insights: #1 The first death occurred without Pete’s knowledge, and it was kept a secret. The Soviets allowed the grim news to leak a month or so later. When an agent goes silent, there can be many benign reasons. But hard-nosed professionals believe that the search for excuses is largely wishful thinking. #2 In 1974, Ogorodnik was transferred back to Moscow and given a desk in the Ministry of Affairs that gave him access to a steady stream of top secret memos and planning documents. And just like that, the CIA’s high-priced investment turned prescient. #3 The spy, Marti Peterson, left her apartment on July 6, 1977, and headed to the drop. She was the first female case officer ever assigned to Moscow Station. She clutched a bag containing what looked like a lump of black asphalt, but was actually a secret compartment that contained messages and a new, improved miniature camera. #4 Peterson was tasked with delivering a package to Moscow, and she knew that the KGB routinely blanketed the city with its operatives. She went through the motions of shaking any tails, and then delivered the package.
