In the post war period I began again to have my doubts about Russian policy.

I was in the underground until I left Germany.

The last time when I handed over information was in February or March 1949.

There is nobody I know by name who is concerned with collecting information for the Russian authorities. There are people whom I know by sight whom I trusted with my life.

Finally Germany's attack on Russia seemed to confirm that Russia was not shirking and was prepared to carry out a foreign policy with the risk of war with Germany.

I was lucky because on the morning after the burning of the Reichstag I left my home very early to catch a train to Berlin for the conference of our student organization and that is the only reason why I escaped arrest.

Before I joined the project most of the English people with whom I had made personal contacts were left wing and affected to some degree or other by the same kind of philosophy.
