Only sixteen months later, in June 1936, the Kirov dossier was re-opened with the discovery of new information. It turned out that in October 1932, a secret organization, including Zinoviev and Kamenev, had been formed.
The police had proof that Trotsky had sent, early in 1932, clandestine letters to Radek, Sokolnikov, Preobrazhensky and others to incite them to more energetic actions against Stalin. Getty found traces to these letters in Trotsky's archives.

In October 1932, the former Trotskyist Goltsman clandestinely met Trotsky's son, Sedov, in Berlin. They discussed a proposal by Smirnov to create a United Opposition Block, including Trotskyists, Zinovievites and Lominadze's followers. Trotsky insisted on `anonynimity and clandestinity'. Soon after, Sedov wrote to his father that the Bloc was officially created and that the Safarov--Tarkhanov group was being courted.

Trotsky's Bulletin published, using pseudonyms, Goltsman's and Smirnov's reports.

The existence of this plot was a major alarming sign.
