Read a memoir by a KGB agent who arrested a man in Moscow who was passing info to the CIA. Had been doing so for years. The CIA had the typical western attitude towards money so they kept giving him stacks of rubles. Thinking they were being generous. The man (a professor, I think) had nothing to spend it on so he stacked cash up in a closet. Had around 1 million stored when he was caught. He probably would have been better off just burning it as the money was used as evidence in his trial.

Had a chance to ask a Russian / Soviet historian how one could spend a million rubles in the late 70s, early 80s. He just shrugged and laughed about it. Almost no way to spend that much. Nothing cost very much and there wasn't much of it.

Yes the movie Night Crossing also shows very well that there was a lot of suspicion, for example they had to buy the fabric from lots of different places and this a slipup actually caused them to be ratted out (not sure if this particular part of the story happened to these people in real life too but it was really a thing)

Yes, was noticing the same. It was easy for them to sell the car and get a new one, so this meant a lot of connections and underground "jobs" for the extra revenue.

Anyways, fantastic story. First time reading despite living relatively close.
