Markus Wolf was the legendary head of the Hauptverwaltung Aufklärung (HVA), the East German foreign intelligence service. The HVA was much better at its work than its West German counterpart, the Bundesnachrichtendienst (BND). Intelligence gathering by the BND in East Germany was of persistently low quality and rarely went beyond what anybody could have read in the newspapers. The reason is simple. Markus Wolf had inflitrated the BND so effectively that much of its activity was steered from the HVA.
