Inner Line

The Inner Line was a secret counter-intelligence branch of the Russian All-Military Union, the leading Russian White émigré organization. General Alexander Kutepov is credited with setting it up in the mid-1920s.
An alternative account sees the Inner Line as a group secretly established by Soviet intelligence within the ROVS.
Whatever its origin, the Inner Line became subject to severe penetration by OGPU/NKVD. It was seriously discredited after Soviet agents kidnapped the ROVS chairman General Yevgeny Miller in 1937, and following the subsequent disappearance of Nikolai Skoblin, who, as a covert NKVD agent, lured Miller into the abduction operation.
